Drunk ex-wife

Five years ago, I was divorced my then wife and we went our separate ways no children but not from the lack of trying. She soon remarried and I lost contact with her, last September, I met her again. Divorced again and somewhat depressed, she still had no children, and her new ex-husband claims it her who can't have children. She never got tested herself and got a good payout as he wanted their marriage finalized quickly. I hadn't remarried and was content just to stay single. Anyway, a week later we met again and we at a business function. I'd come alone hoping to leave early, meeting my Ex put a stop to that, as she clung to me for company and drinking anything and everything that she was offered. I drank only beer, and she had 3 or 4 drinks to my one. Anyway, I got bored and decided I would leave, and my Ex could stay. But on being told I was going to leave; she asked me to take her home. So, I did on getting to her place I was invited in for a nightcap. She told me she was very horny and asked me to stay the night with her. I decided to stay, told I didn't to take precautions, I didn't. We're marrying again February 8th, turns out she can get pregnant, and I just happened to fuck her at the right time. We stayed friendly after our divorce and marrying her again wasn't a hard decision for me to make. I've always enjoyed sex with her, and she is very willing to have sex. Her depression has left her since becoming pregnant. She informed her second husband on becoming pregnant, it might not be either of their faults, just wrong timing. As it appears to have been in our first marriage.
