What should I do?

Hi, please don't judge me regarding this...

I'm in a really messy situation right now, I just broke up with my bf of 4 years (the whole time it's long distance relationship we never met in person) and I know I have to break up with him because he was harsh and he keeps on promising me things that never come true. But I miss the good times with him and it's making me so sad and lonely....

However, before I broke it off with him a good friend that I know since primary school came home after 4 years abroad. The thing is me and this guy, we always have something, like a connection. When we met up it's like we've never been apart and eventually the physical affection came back too, no sex just holding hands, hugging, kissing, etc. It was too natural for us. The problem is I had a bf and he STILL have a gf when we started all this (I broke it off with my bf not entirely for him).

He's going back to the US in a few months to sell all the belongings he got left there and he told me his gf is coming back with him to our country just for a short vacay and its driving me insane. He keeps on making me confused, he told me he's with her for the green card but then she's coming with him all this things he's saying is confusing. He can propose to her in 2 years because she just got her green card.

He kissed me but he brought up his gf in our talk too which upsets the hell out of me.

He confessed to me about his feelings a few times when we were growing up, I had feeling for him too but the timing is always off. We even made a deal that if the both of us are not married to anyone when we are 30, we will get married. He brought it up when we reconnect.

What should I do? Should I keep on going out with him and stuff? What we did is it considered cheating?

I want him to choose me, I'm trying to help him build a life here but idk...

Please help... this is bothering me so much I can't eat, I haven't sleep too.
