<human>: I [22M] broke up with my gf [20F] like 2 years ago and she went to USA to study but she came back to México after 1 year. Our relationship lasted for 1 and a half year but we didn't broke up in a bad way so we started to go hang out like friends, but obiously we ended up having sex. 

We talked about "us" and we both agreed that we won't be a couple again. 
But we keep talking to from time to time and suddenly we ended up saying that we wouldn't be talking to each other again and again and again mainly because we get tired of each other's bullshit but we keep talking rofl. 

The issue is that I always think of her and want to be with her like the old times but when I go out with her I end up disliking it, also she doesn't want to share her thoughts completely but I know she's in the same train as me.

Can you summarize the given text in a few sentences?
<bot>: We both like each other but we don't want a relationship, we enjoy sex but hate discussions so I don't know if I we're horny or in love.
