Another advice from a "mom" You have plans for yourself . A boy freind gets in the way, I know I married at 17 thinking I could purse my career of training search dogs. Wrong hubbys things can first. I don't regert my life 25 years of happy and sad times. I now am working on a search dog now for me and for fun.
My daughter has fallen in to the same trap as your friends and now at 21 is tring to get out of a BAD relationship. They started living to geather and buying a house now she wanis out and keep the house . She coesn't make enough to keep it alone.
Just keep your eye on YOUR future and the right person will be there and ready to accept you as yourself. Not what you make yourself to be just for a guy.
Keep your chin up and just have lots of freinds to do different things with.
You are a very pretty girl.
