Does my ex really not love me or could this just be a last shot at adolescence fueled by hormones?

Ok, so heres how everything happened with as much detail as possible. first off, my ex is 19 and im 26. Granted that makes for a large difference, but we thought our maturity levels where in tune with eachother. anyway, one day she texts me and says she wants to break up. we get into a phone conversation about it and i tell her to tell me that she doesnt love me so that i can move on. she refuses because she says thats just mean and its stupid and she wont do it. ultimately she does it and we decide to meet up the next day to exchange things and money that id given her for our trip to Utah the next month. we meet up that day and after seeing me she starts crying and says she doesnt know what she wants and doesnt want to lose me. so we stay together with the stipulation that we dont have titles but were still everything we ever were. i was happy because i though this meant she did love me but wasnt sure what love really meant. in that following month things seemed fine until we found out that she was pregnant. we talked it through and i had said that if she wanted to break up then id understand if she wanted an abortion. shes an ex mormon and just doesnt believe in them, but we both knew thats what she really wanted. we decided to make our relationship official at that pointand keep the baby. she told me that one of the main reasons we broke up was because she thought i couldnt have kids and that was very important to her. so time goes by and we go to Utah. I propose to her and she accepts. things seem fine. a week after we get home her gay male bestfreind suddenly becomes single and she starts spending waaay more time with him. supporting him in his time of need i suppose. wed talked about that before...that whenever shes with him she decides that she wants freedom and things that he has and does. she told me she would avoid it. im a very easy going guy and im not about to let her cast aside her best friend for my comfort. so within about a week i get a text message from her saying they're going to a gay bar. i dont take that news well, but i say nothing other than be careful and have fun. the whole night shes sending me picture msgs of half naked people and general club goings on. by around 130am i get pissy about it and call and remind her that shes pregnant and has her first sonoram in the morning and shouldnt spend too much time in those places. it goes on for a minute and she decides to freak on the phone, saying im not her daddy and i dont have control over her and she litterally sounded like another person. she was channeling a 16 year old prostitute. she says that shes tired of all of this and doesnt want the lifestyle anymore. i freak and try to head over there but cant get out of work. the very next morning was supposed to be our first ultrasound, so i go straight to her place after work that morning and her and her gay friend are asleep in her room. him on the floor, because i had mentioned i dont like them sharing a bed. we go to the appointment and instead of the ulrasound we see the dr about abortions. it seems set in her mind that shes not keeping it. all through the rest of the day shes treating me lik crap, so i ask her if theres something going on and if she would like to break up. she starts crying and says yes. shes tired of treating me badly and she says that we never cliqued as a couple. i say fine and we have our goodbyes and i leave. i catch her mom on the way out and tell her we broke up. for some reason i break out into tears with her mom but not her. on the hour long drive back to my place i txt my ex saying i cried to her mom and im sorry for everything i hope her choice to be alone and be without the baby makes her happier than i ever could and goodbye. she then sends me a worried text saying dont leave her forever, just give her time. i took a minute to reply so she called me and says the same things..just give her space and dont leave forever. the next day i try to talk to her about it al and she completely flipped her opinion. she says she never loved me and theres no chance we'll ever get back together. im killed inside by that and was lost for days. in all honesty, i did pesture her through texts in those few days after that and she got mean. within th efollowing days we chit chat through txt as if nothing had happened. we set a time to exchange more stuff. she invites me in as if all is normal and we go to her room, which freaked me out, and she sits me down on her bed and shows me a sonogram. she says shes keeping the baby, but does not want to have me in her life. i can be there for all the appointments and she wants to be civil for the child but doesnt want to date me at all. still doesnt love me. i just dont know whats going on here. she says she had her doubt before she got pregnant, but when she did she said al kinds of other things like that was mainly because she thought i was sterile and she wanted kids. im completely torn up about this
