I'm 28 years old. I broke up with my ex a little over a month. We dated for almost 4 years. I had a lot of feelings for him and still do. From the sound of it he doesn't have a problem with talking to or being with another girl. Maybe it's a guy thing I don't know. When it comes to me I feel guilty if I date or consider dating another guy. A new guy has taken an interest in me but I feel like I'm cheating even though I know in my head that I'm not. Why? What's up with that? I don't get it.
