Hi OP,
I totally empathise with how you're feeling. It sounds to me like you know your decision already, perhaps?
I had a termination 11mo ago and wanted to share another side - I found out I was pregnant and I knew instantly it was the wrong time, too early on in the relationship (7mo in..), not quite financially secure enough etc.. anyway, what I'm saying is I didn't even ask my partner, because I just KNEW - not the right time, definitely want to be a mum but it just all felt wrong.
Anyway - from what I read on here about women who regret it, or women who take the first pills then frantically change their mind and hope it hasn't worked etc, the thing they have in common is that often the seeds of doubt were very much planted, they were maybe doing it because a partner had encouraged it, and they weren't like me (e.g, knew in their gut it was 100% the choice they needed to make)..
What I am trying to say is that whilst it's not binary and black and white, you could well abort this pregnancy and go on to be perfectly happy with your choice, having babies down the line, or you may have regrets, but your post reads as though there are no real reasons not to keep this baby? I think you maybe have your answer and are looking for reassurance?
I think his issues about the son seem a bit weak and I 100% agree with the poster who said about men coming around to it. I've read lots of threads on here about men who are instantly shocked/against it and then come around to it in time - I agree that it takes a lot longer for them to accept it, and sorry to stereotype but I think a lot of men even when in settled relationships and financially secure/married will still drag their feet about committing to having a baby..
I think if your relationship is solid, that is far more important than the practicalities (obvs I know finances etc are important..) but baby will put a strain on things so it's definitely worth having hard conversations at this stage such as how happy / committed are each of you, even if we took the pregnancy off the table, etc? Then at least you know how strong your foundation is - family help is fab but ultimately it will be the two of you going through this together..
Have a good read of threads on here where others have been in your shoes and also some of the 'accidental pregnancies, do they come around?' type threads!
Keep us posted please on what you decide!!! X
