relationship advice ASAP please

so I had this boyfriend for 3 months met his parents and everything then out of no where he said he'd rather have me in his life as a friend then loose me because he's been a cheater in the past. We basically stayed friends with benefits for 6 months but he got a gf a month ago but continued talking to me he said that they have intercourse but still wanted me to sexually please him. It was never in person just through text and at first he felt guilty as did I but he continued his feelings we're getting so mixed up as mine that I decided to move to another country. I thought after a few weeks he would forget about me but it seems the longer I've been here the more we talk but no longer a sexual way, more like remembering our time we dated. I don't understand what's going on, and I'm heading back in a couple of months he doesn't know this tho. The hardest part is that I can't and I don't want to distance my self from him because we have the same friends literally. It scares me tho because I want him to be happy with whatever girl he chooses so I try my hardest to stay away but when we see each other there is literally this force between us that we can't help but look into each others eyes or enjoy each others laughter. He also has stated many times we need to stop this flirting and remembering things I would prefer zero communication. So I agree but he says that he wants to stay good as friends wich is completely confusing. Never the less he's always the first one to talk to me again. At one point he got mad because his friends invited me out with them and almost cried because they were "fu#king with his feelings" wich confused all of us since he apparently has no feelings for me. Once I left the country his gf left to the army as well I realize at first he may have just contacted me for sexual pleasure. It has now been at least 3 months tho and he continues to contact me but this time like I said just remembering the past and we talk from 9pm sometimes till 4 am. I don't know what's going through his head. I need help to understand the situation does he want me and just can't admit it or he doesn't even admit it to himself or are we just meant to be friends and later on get over each other . I know this is long I'm sorry but I have been single for 8 or 9 months now because I can't find my self having feelings for anyone else but him.
