Attached to him

I’m 18 I’ve been together with my boyfriend for about 8 months we live together at my house with my family it’s fun and all but sometimes I just want to relax with him and just hang out but he wants to go upstairs and sit around my family and they don’t even talk he’s just on his phone like he could be going that in the bed he just got back from being a way for a week yesterday and it’s like he does not really wanna spend time with me
