I dated this guy and from the beginning we both had different views on what we wanted. I was looking for something along the lines of a relationship and he wanted us to be friends for awhile before the word relationship came into play. So at the beginning I went along with him and let him know that my options were still open to other guys, and basically no boundaries were set. We probably dated for 2 and a half months until I met my boyfriend or potential boyfriend (pb) at the time. When I met my PB, he was everything the old guy wasn't. He wanted to date and he actually pursued me because I wasn't interested at first, but he won me over. I gradually pulled away from my old guy because I knew at the end of the day we wanted different things (and I wasn't about to sit there and wait for him). Now that I'm finally happy in a relationship, the old guy keeps calling me and thinks can come back into my life like nothing has changed. He's (old guy) mad because I got into a relationship. I actually think he thought I was going to be his friend forever. I've told him I'm happy and my new boyfriend is getting upset because he's calling at all hours of the night. How do I resolve this so he (old guy) can leave me alone for good?
