Rules of Not Dating

Ok I know how completely insane this probably sounds but I can't take it anymore not only do I need to vent about this but I also need some other opinions. See it started a couple months ago, my life was normal. I went to work everyday and complained about it everynight I was a content, strong woman. I was independent. I didn't need a man by my side to prove anything see, I had been through a terrible breakup and I was still coping a bit from that when my grandmother suddenly passed away. I'll be honest with you I didn't know how to feel, There was a young man in attendence at her funeral due to the fact that she was in the local fire dept. he was a member himself and apparently I look good vunerable, because the day after my grandmother's service he started talking to me then we had this fantastic "love affair" I still talk to him and I still see him just not nearly engough anymore then his ex girlfriend decides to invite him to her birthday party? and he goes? I'm probably over reacting but my god! you picked me up at MY Grandmother's funeral and now u ingnore me for your ex whom you told me was too clingly seems like I can't win and the worse part is I did get attached he's smart, funny and sweet but apparently it doesn't matter. Here's the lesson I've learned, no matter what never let anyone, especially a man take you, that strong, independt woman is still in there and hey maybe if you are able to get past the fear that he is going to dump you for her then that side might show through more. I refuse to let him take everything from me.
