I am now grieving the fact I am infertile and can’t have anymore children. I had a hysterectomy 3 years ago. I have children but it’s opened a huge wound that I am still so young and can never have another baby and it’s brought home the fact it may be a huge barrier to me meeting someone else.
OP, this was in your first post on the thread. I don't want to dismiss your feelings on never being able to have more children, I felt the 'need' to have a second but I'm done now and have no desire for a third. I do understand your mourning your fertility though.
But what stood out for me is the feeling you have that not being able to have any more babies would be a barrier to meeting a new partner. Please be assured that in my experience (divorced when kids were 7 and 4) that if you're upfront about your situation - can't/don't want to have more children, it really does weed out the blokes who are actually OK with that and those who aren't. I suspect that he might be using the fact you can't now as an excuse to get out of the relationship, and that is despicable. Never mind the drugs, sex workers.... Its not like you have decided not to, then changed your mind, it's a non-negotiable of the highest order.
I've spoken to several men that when the kids conversation begins, visibly relax when you say nope, no more for me! And then there's the worry-free sex (after std testing, of course) to enjoy without worrying about contraception! They may already have kids of their own, or not want more. If, eventually they do change their minds, a good bloke will at least have the balls to own that decision and make leaving the relationship easier on you.
Please think about some counselling for your feelings about your fertility;it is something you need, somehow, to come to terms with before embarking on a new relationship. No relationship should require you to have a baby with him, babies do not cement a wobbly relationship. And the 3 children you do have need you, as much as you need them.
Oh, and your ex sounds like a real piece of shit - drug dealing, flaky, emotional abuse... Move on, when you can, there are plenty of good men out there x
