Its a long story so I'm going to put it in bullet form for a quick read
• we met at this clothing store this past December
•began talking/texting a week later, 2weeks later started going on dates
• had sex in January also found out he had a girlfriend so I chalked it up as a lost and kept it moving
• he knows what happen but he still keeps texting me...once a week and its getting annoying
•the sex was wack so its not that and i cant change my number because I'm involved in a lot of college/community service ventures to try and give out a new one
•any advice or better yet tell me why dudes do that? Its kind of creepy
