My boyfriend has changed his mind

My partner and I have been together for 3 years and after a year I fell pregnant unexpectedly. I was devastated, I just wasn’t in the right place and neither was he so i agreed to get an abortion with the expectation we would try in the future (I’ve made it clear multiple times that’s what I wanted).

Well fast forward two years and me coming off all birth control and starting to relax protection and beginning to track, he has decided that he really doesn’t want another baby (he has 2 children from a previous relationship). I’m an emotional wreck!!! I have a daughter from a previous relationship but I really had my heart set on having another baby especially having to go through all that last time. Maybe if I’m honest the abortion was more his idea than mine and I didn’t feel completely secure in the relationship at that time.

My question is do you think I will always resent him for this and would it be best if I just moved on to give myself the chance to have another baby. I do love him but I just feel so betrayed like his promises meant nothing.
