A little background: I have an Ex from my first year of college (about 5 years ago), and he was my first love. Our relationship was very passionate and I will never forget it. At the time we broke up, we were both still very immature and realized it just wasn't the right time to be together.
He decided to take some time off and travel after our sophomore year, and I stayed and finished my degree. And he has always stayed in touch... not just sexually but as a friend (sometimes he even helps me with current boyfriend problems).
I've had countless relationships since then but one thing that always remains the same is that my Ex always stays in touch. Sometimes he could be in constant contact for a few months... sometimes I won't hear from him for a bit but then he will surprise me and call me just to chat like nothing has ever changed. And he will mention the pact we made that when we're 30 if we are both single we will get married, or he will jokingly ask me to elope with him and say that I am his source of optimism.
Right now is one of those times where he is in constant contact. I have a boyfriend AND he has a girlfriend but he has been calling me almost every night for the past couple weeks. Most of the time I don't answer even though I want to.
I really don't know what to do because I am happy in my current relationship, but I also feel guilty having another guy on my mind. Is there a way to ask my Ex why he has always stayed in touch and a way to get him to tell the truth? And maybe get him to back off?
