Social media

I've been with my boo thang for a while now and we live together. There's something bothering me about my relationship we were friends on social media than when we fight he blocks me ? I thought it was weird so I decided to go through his phone . I saw him liking many girls photos and ( btw he never calls me beautiful or anything ) and I found no messages or any convos with other girls. But I found he had a second account on Facebook with a different name but like a meme photo, but couldn't log in . Am I being paranoid ? Should I feel like we should be on each other social media? Am I crazy for thinking he is hiding something ? He is the one with trust issues and always goes through my phone . Uqhh I need advice really!!!
