Whisper, I hope you and mister can be happy in each others arms again. Arguments are rough and if you are anything like me and my dp, we don't argue much, but when we do, it is epic.
I was thinking about him wanting to talk to someone different, and I suppose we have each other, so it is understandable he has somewhere, but perhaps he could try dadsnet instead of a dating site. That way, the insecure hormonal pregnany lady inside you won't create suspicions where there aren't any.
Finances are a big thing for is too. I want to go away for a couple of days in October as a kind of banymoon, but we have so much to do to the house before the baby comes, not least stock up on some of the last bits and pieces that we would both feel guilty spending money on something we won't get anything back for. At the moment, i am looking into a murder mystery night somewhere not Bristol. That might be enough, especially if we stay an extra night. But money is the devil's tool and usually can be found behind most aguments.
As I said , I hope you both kiss and make up today. You need each other.
