Title is the tl;dr. I don't trust her, but I don't know if it's be overreacting or if the red flags are telling me something. She's obsessed with social media, gets DM'd constantly from guys, I've seen her lie to other people about things and is really fucking good at it, and never puts her god damed phone down.

I just don't know how much longer I can take this. Either I have to change immediately or I have to end it. Every time she picks up her phone it goes through my head that she is talking to some dude messaging her online. Today she is going to look at a car at some car dealership where her friend knows the guy selling cars. It's going through my mind that she'll be flirting and what not.

The girl spends money on me constantly, we have a great sex life, and she stays with me most nights.

Am I being overly paranoid? In other LTR's I've been in since TRP I have been much cooler and more confident, but I don't know why this one has been different. I really think it's the social media bullshit, but those red flags above are still valid aren't they? Is it a scarcity mindset? There are other chicks I could bang, so I don't know why it would be a scarcity mindset?

Any advice is appreciated.
