<human>: Was dating this girl, lets call her Sarah, and things were great. I really liked her, she really liked me, we have huge mutual respect, the sex was great, we said we loved each other, we were talking about moving in together.

Then she broke up with me and disappeared, totally ghosted me. I was shocked. I tracked her down and we talked about it. She has anxiety, she can't handle a relationship, the future scares her, there's too much pressure.

I told her none of that mattered i want her in my life no matter what, even just as friends, i really love her. She was happy to hear it, we were getting along great as friends.

Then we started sleeping together again. She was super affectionate, attentive, texted me every day. we were even closer than when we were officially dating. needless to say it was a bit confusing...

And now she's begun hooking up with other guys via tinder. it feels like she's cheating. we might be unofficial but that's hardly the way she's been acting... and it's never the way i've acted.

i'm not sure what to do... should i tell her we can't fool around anymore unless we're exclusive? should i tell her we should give dating another shot?

i don't know if i can take her back after ghosting me, if she does it again i don't think i can handle it... 

but being 'just friends' with no benefits and seeing her with other guys, even just hookups... i don't know if i can handle that either...

just looking for some advice. some anecdotes... we really love each other, but sorting out what can actually work with her anxiety has been tough...

thanks

Could you distill the essence of the text into 1-3 sentences?
