Unsure about my relationship

Im currently 15 weeks pregnant and im unsure about my relationship. I met my bf 2 years ago and it was rocky at first and i still stuck around lately things were getting back to how it was before it was alot of demanding and it seem like it was always him first so i said no im putting my foot down i had this long conversation with him and i told him i was sick of his shit to get out of the house and when he was ready to change we could talk.

Now its only been a week hes been calling none stop n he says he's ready that hes sorry that its not going to b about him all the time hes not going b demanding all this bs i wanted b4 BUT im not sure if i still want to b with him now. I try to talk to him but it seems like he always wants to sweet talk to me and he actually trys to do everything i told him to change but deep down i have a feeling im making a mistake im just not sure about this relationship i just think its been 2 yrs already i dont belive people change

I feel bad bc ive told him this is not working and he trys even harder to do something for me now i act like such a bitch i dont think a week is enough but there he is hes buying things for me gives me his whole paycheck rubs my feet. I have mix feelings about everything Idk if its my pregnancy or me.

I need some advice
