Ok, so I am 18 and my girlfriends is 16.My girlfriend and I have been together for a little over 8 months. We have had a great relationship and make each other very happy. However I am troubled by the fact that she has been involved with another lover before me, he was very controlling torwards her and she still did a lot for him. When they broke up he began starting rumors that she was a stoner(pothead) and a "backdoor virgin" which really bothered me and still does quite frequently! She tells me how much happier she is with me, she also never talks about him but I just feel as though because I was not the first guy she was involved with that I can never impact her as much as he did. Also before they broke up she made out with another guy because she began to care less and less for him also. He never paid for her on dates, like I do. Plus he uses his moms money to buy marijuana and alcohol and I have a job and live on my own because I have not much family I'm close with. She is always telling me she loves me and is always happy, however I feel as though I weigh her down due to my money problems or personal issues at times. I just want to get past my problems that I'm currently struggling with and move on happily with her. I just need some advice please!

Dude seriously the past is the past can't change it. You either accept it and move on or let it eat away at you and destroy your relationship. Choice is yours.

Reading this is crazy weird! So I had a girlfriend. She is 16 and I am 18. She had a previous boyfriend who was the same way. It bothered me a lot knowing that she had sex with a couple other guys before me. You have to realize that they don't mean **** to her now! Because she is with you know!! Trust me I really know exactly how you are feeling. I would sit in class and think about her with another guy, it drove me crazy I wanted to kill them. Just for treating her like **** and for having sex with her. It makes the hairs on my back stick up just thinking about her with another guy. But she wasn't with you then. And she is with you now! Remember that.. My girlfriend and I just broke up this past Friday. Read my blog I don't know this feels like how I was at the beginning of my relationship. Hit me up I don't know I feel like I can help

I think you worry too much for nothing. The fact that your girlfriend had sex with someone before you doesn't mean anything.
IMO, you will have a greater impact on her because you treat her right. And according to your words, she appreciates it.
Think of it this way, in sometime from now, when she'll look back, who do you think she'll remember of? A stupid pothead who treated her like trash or a boy who treated her like a princess? I would go for the second one.
