DP went out last night, absolutely fine, he would normally be back midnightish but know this can be sometimes like 3 when him and his friends have a good time and end up at a club. I don't sleep great when he is out as I'm sort of waiting for him to come in and aware he hasn't. Called a couple of times at around 3.30 and he called back shortly after, said he was fine they'd all gone back to a friends house and he'd be home shortly. He messaged at 5.30 to say sorry he'd fell asleep, back shortly. It's now 9.30 and still not back. I assume he's fine and managed to get a lot more sleep than me, I feel like I haven't slept at all. I don't think there's any funny business happened and he is just on a friends sofa. We have lunch out today booked with some of his family though, AIBU to now not go, I feel and look horrendous and slightly peeved at his selfishness as I'm nearly 20 weeks pregnant and he knows how I worry if he stays out all night, luckily it's only ever happened once before.
