How do I forget??

Heres my situation: I was with this guy tyler for a long time, we were together for months! And I thought he loved me, at least he really liked me.. I was a virgin when I met him, soon as we did have sex, about a month after, he left me.. He didn’t really even break up with me he just ignored me, (we weren’t even really going out because he said that it would never work because we went to different schools)

In the beginning: I met him in summer school and he still did everything he could to keep in contact with me long after summer school was over, we would talk every day for hours and hours on the phone.. Sometimes we had phone sex.. Then one day he made it so I could see him, I snuck out and went to his friends house who lived just down the street, and he was there waiting for me, he was so charming and awesome that I ended up giving in to him. After we had sex, he would call me every day he even said he loved me, but then about a month after I gave it all to him he completely ignored me.

Now, I have a new boyfriend and everything is awesome, I love dalton so much! But just the other day, tyler called me and we started talking and one thing led to another and we had phone sex… Then he told me he was sorry for not talking to me, that he was just busy with school and family.. And that he wanted to see me soon because he misses me.

Just the other day, I sent him a message on a social site saying I wanted to see him, and he never replyed, I know he read it. And then I went through his a social site thing, and I found out that he was with another girl the whole time.. Ad he has ben for a while.. I really did love him.. I know I shouldn’t have fallen for him in the first place, but it was hard not to..

I dont know what to do, I want him to talk to me, I thought I was completely over him, and I would have moved on, but he called me the other day… And now I cant stop thinking about him.. I dont want to let go, but I know I need to because hes obviously moved on, and now I have a new boyfriend and have been with him for a while and I love him, but I still have attachments to tyler.. How do I forget about him??
