Feel like going MIA

Boyfriend and I have been fighting a lot recently and I just feel like things aren’t the same anymore. Now he wants more space from me he doesn’t text me the he would and last night he claimed he was doing an essay but in reality he wasn’t I have no idea what he was doing. I hate that I feel like I’m the only one who cares. Why can’t I be like him and just not care anymore either. He keeps doing shit that makes me worried and anxious. I feel like turning off my phone all day and seeing if he even notices or cares
