I've been with DP a number of years but don't live together. DD was at primary school when we met and she's now a young adult.
They rub along ok but are very different. He's loud and outgoing and he likes a drink (sometimes too much but that's a story for another day) and to be sociable. She has ASD and anxiety and is quiet and she doesn't drink. I therefore tend to do things separately with them, although he often stays over or I cook for him or we'll go for a meal or the pictures or a museum together.
Later this year I'm spending a few days away with DP, a few days away with DD, a night away with my DSIS and two separate short breaks with two separate groups of friends. He went in a sulk because the break I booked with DD is over a weekend where we could possibly go to a sporting event together.
During the argument I said "get a friend to go with you. My life doesn't revolve around you, sometimes I do things without you" and I realised that's the problem! His life does revolve around me! He had one good friend who moved away and he has another friend who is a flake. He has no friends from work etc.
I can't force him to make friends or to do stuff without me. I love him very much and I love doing things with him but I also love spending time with friends, and I like spending one-on-one time with DD. So wtf do I do with this revelation?!
