Been with my DP for 3 years. He's lived with me for 6 months but also has his own flat a 40 min bus ride from me (we are in London). We've been discussing renting out his flat, marriage plans and just booked an expensive once in a lifetime holiday for the summer. We are mid 30s if relevant.
We had an argument yesterday evening around 7pm - I was annoyed he wasn't doing more around the house. Despite being super clean/tidy at home, he doesn't make much effort since living with me. Obv a concern I want to address before we go down the marriage path. He got cross and told me he was going back to his flat as didn't want to talk about it anymore. Fine. He does this sometimes if - will either go for a long walk to calm down or go home for a few hours to get some space. Tbf he hasn't done it in a long time since I told him I don't mind the long walk to think things over but think going home is unnecessary drama.
This time however, his phone is switched off/unavailable which is unlike him. And I haven't heard from him since he left. He's never awol like this all evening/night and we always talk and resolve things after an argument after a few hours. My first thought was to be pissed off that maybe he's being petty/punishing me for nagging him (even though it's unlike him). But it's now 6am and his phone is still switched off, he hasn't been online since early afternoon yesterday, and I'm wondering if something happened. He's not usually active on social media so no way to check that.
I'm debating going to his flat to check now (which would delay me for work) but also don't want to give him the satisfaction if he is indeed being petty. If I do go into work though I'll be 2 hours away from his flat with no way to check on him till evening.
He wouldn't be at any friends as none live close by, he doesn't do drugs and even when drunk always remembers to charge/have his phone switched on. He's on days off this week so no need to be at work. What would you do? Check on him or leave him and wait to hear from him.
