Search Results: don''t want to be serious

My sister recently went to a high school gathering for a teacher she had and it so happens that my EX of about 5 years ago was there. Full disclosure there hasn't been a day in which that girl doesn't cross my mind. Point is she asked my sister if I was dating and that she heard that I was practically engaged (no idea how she heard that but so far off the case not even close). I was surprised she actually gave in to ask about me, I don't know if I could have done that. WELL all i wanted to know was why would she ask that, maybe she was just trying to make small talk with my sister since they are friends. She mentioned to my sister she did date someone in college but things didn't work out between them. I am currently dating a great girl but I've been unsure on how our relationship will go when its time to turn it into something serious such as living together because we are such different people. Im not asking for someone to tell me what i want to hear, I just want a girls honest opinion. I haven't messaged her in years last time I did I congratulated her on graduating High school she opened the message about a year later at 2 am. So I dont know if i should even try to contact her or "run into her". she's only going to be here for the summer she goes to college across the country from where I am at.
