I liked a guy and told him so. He responded positively but nothing happened because I went away for awhile. We continued to flirt and he said he would keep in touch but he hasn't. Seven months later and I am going back soon. I guess if he hasn't kept in touch, he's not into me. So, if I see him and he says "sorry for not keeping in touch," what do I say. He's flaky and I think I want to give him another chance. I opened up to him and told him how I felt and he just disappeared.
