Well, the first reaction I got was genuine laughter, I'll never forget it. I told him in the backwards in coming forwards words of "We've got a problem. A 9 month long problem" He found it hilarious and said "Nah, you've not got a 9 month problem cos of me like" but after I assured him that I definitely did, he was actually pretty nice and calm about it although I made the mistake of telling him when he was drunk so the next morning when he woke up, he'd forgotton all about it.
The second reaction was "Oh no, don't tell me you're pregnant!" and staring into space for a good 20 minutes before I had to break the silence. He suggested abortion (more than once) but I told him quite clearly that wasn't going to happen, however, I also said that if he didn't want to be involved that he could let me know there and then and I would leave, raise the child myself and wouldn't ask him for a thing. I don't believe in forcing anyone into parenthood because if that happens, everyone including the child just gets hurt. When I said that, he told me loved me and wanted to be with me so he'd "have to get used to it" - that sounds bad but with the way he said it and the person he is, I knew that it meant he needed time to settle with the idea and that he himself recognised that.
So after about two weeks of talking to his friends, talking to me and and changing his mind about 5 or 6 times, eventually he turned around and said that he wanted the baby. We've even talked about names and he's said that he wants to live with the baby to be able to take care of it and bond.
His face at the scan was priceless. Even more was the reaction to finding out it was twins! The exact words of "Oh my God" will stay with me for life. Also, "I'm more chuffed that it's twins" just shows men think of some things in very weird and wonderful ways.
So, I guess that was a long winded way of trying to say that sometimes men react on fear of change and the "omg, I've screwed up!" mentality leads them to avoid the entire situation for a while. But if you have a bond with someone and you both genuinely care for/love each other then you have the best shot you can have at being successful parents and a successful couple.
