I actually sympathise with him a bit. 16months is really bad, don't get me wrong, but DP rarely looked after our son alone for a long time. Not because he wasn't capable, just because he didn't need to. I didn't work and hardly ever went out. When we were together, we were ALL together as a family. It just never came up.
But it came with a massive downside. He never learnt DS's routine, didn't bond with him like I did, didn't understand the hard work I put in everyday because all the little things I had to do for DS never even entered his mind. It also ment he had no confidence in his ability as a parent and it scared me a bit. What if I got hit by a bus tomorrow and DP had to be a single dad? He wouldn't have a clue, not because he didn't want to, just because he had never had the opportunity.
We argued about it once and he snapped at me "well you never LET me do anything, sometimes I don't feel like he's my baby!" and that really upset me. I just did everything, without thinking to involve DP.
So, I went back to work last summer, and DP is at uni so he gets the school holidays off. He had DS all summer, he saw him twice as much as I did, and I forced myself to take a step back and let them get on with it. Their relationship changed so much. They are so close now. DP knows just what to do. I can leave without giving instructions and I feel that we are equal.
Still, I think this guy needs to realise that it's not all about him. He should spend one to one time with his daughter for HER sake, not his. Also, his poor wife must need a holiday if thats the first break she got in 16 months. I don't think he's a bad father, I just think he's ignorant.
