So, I'm 43 years old and have had infertility for over 20 years, I had a few miscarriages in my late teens but no pregnancies ever since, I went to see a fertility specialist a few years ago snd they told me I was infertile and would need ivf but said that even that probably wouldn't work, she gave me leaflets on surrogacy and adoption on my way out. Fast forward to this February and l fell pregnant completely naturally and out of the blue. My boyfriend has already two teenage daughters from his previous relationship and didn't want any more, obviously I had no expectation of ever being able to be mother and I don't think I would've chosen to be now at this age and situation in my life, so neither of us had ever bothered with contraception in ten years. He now blames me, he thinks that somehow I've tricked him, he says I must've known I could get pregnant, he isn't being nasty to me but he does think I've deceived him which obviously I haven't. I'm angry at his not believing me and for his misogynistic view that it must be the woman's fault, I honestly thought better of him, I'm now considering leaving him and moving away, am I overreacting here?
