<human>: Hi everyone, I'm looking for some good advice about getting over this massive issue I've been going through.

I have always been very insecure, every relationship causes me to go into a mental tailspin where I have to validate in my own mind that the other person isn't cheating on me.

I've been seeing a really great person since early April, he's attentive, sweet, genuine and has never really given me a reason to be concerned.

I find myself going into panicked tailspins daily over nothing. I go over messages he's sent me time and time again, picking apart the wording, go over what he's been doing that day to ensure he didn't have time to cheat, just general insanity. 

Tonight I was on facebook and saw a pretty girl he happened to be friends with and noticed he had liked a fair bit of her profile pictures (he frequently likes ones cousins, close family, other female friends pictures as well) and had a panic attack.

I fully realize how insane and unhealthy my behaviour is. Relationship or not, I don't want to live in this constant state of uncomfortable anxiety. I don't want to find myself trying to go through his phone or online accounts once I move in next month or freaking out if I see old condoms in the back of one of his drawers.

Please tell me some words of wisdom or give me some advice so I can move forward

Thank you!
