Hi, need some help here. So me (22F) have been with (let's call him Tim for anonymity reasons (29M) for about 3 years. We've had a pretty rocky relationship and he's mentioned at several points that he wants other people, wants to be single, etc. Then we get better and he says otherwise. And back and forth he goes. So recently, l've noticed he's been a bit weird about me looking at his phone while he's on it, or about me even having it. I also noticed (yes I'm this paranoid that I pay attention to details like this) that I never notice any Snapchat notifications pop up on his phone, and I frequently see him active, then inactive for a few, then active again on Instagram, all while not responding to my texts and saying he's doing etc. His follower and following count keeps going up, as does his snap score when I don't really see him even using snap at all. (I know I sound so crazy...) I don't really know what to think, maybe l'm being super paranoid and anxious. I just wanted to post here and see if maybe I'm being too paranoid, or if I do have a valid reason. Should I check his phone?

Edit : I just wanted to add that recently we've actually been doing much better than we ever have, which makes me feel like he has less reason to do so

Edit 2: He's brought up wanting a swingers lifestyle, which I'm ok with, I guess, and we've tried it. He says that would be enough for him and that because of that he has no reason to cheat on me etc.

TLDR; I've noticed my boyfriend doing some sketchy things with his social media and think he
