You asked for a man’s opinion, so here is one:
After a painful divorce, ( She had an affair ), and after a good period of time, concentrating on my children and getting my head straight, I met and began a relationship with a lovely lady who had children the same age as mine. I loved them all and treated them equally.
But over time, geography amongst other things forced us apart.
Like your BF, I’m in the later stages of middle age. My children are men with their own families. My grandchildren are my most precious joy.
But if I was in a similar situation to your BF, and a partner / you said, ‘ I want children or I’m leaving but I’m giving you three months to mull it over, with the result being if you haven’t changed your mind and agree, I’m off ‘
My reply would be, ‘ No need to wait three months, I’ll help you pack now. I love you and I respect your decision. Good luck, good bye ‘
Many on here, ( Mostly women, I guess ), have said / advised leaving him to fulfil your dream and desire to have children, and that’s great advice.
But you have no idea about children or raising them and how they completely change the dynamic in a relationship, for the most part. He has.
At the moment, you have no idea about how exhausting sleepless nights can be, your social life will centred around a new born, the emotional and financial changes that ensue, he has.
People say you will resent him if you stay and miss the opportunity to have children.
If you get your way, he may well resent YOU and the child.
