One thing you need to know about me is I don't always give LOGICAL advice. I give advice based on my own experiences and sometimes, what I would do. It certainly doesn't mean it is what a Psychiatrist would tell you, and it's quite possible no one else will agree. I just hope you don't take this as me trying to cater to your insecurities and tell you that it's all fine, because that isn't the case.

I guess what you are going through could be considered insecurity. However, as an insecure person myself, I can totally relate. Luckily, the girl of my dreams had never intimately been with anyone else. Or at least from what she told me. I also never was in contact with anyone that claimed to have slept with her, or any of that nature. Mind you, I have only had ONE "girl of your dreams". I have been with many others, and all of the others had other sexual partners and it didn't bother me. Granted, though, I wasn't in LOVE with them.

Had my ex and I had these types of issues, I don't know if I could have handled it. It is certainly disturbing that you had to see all of these different things. It is almost like someone is trying to sabotage the relationship, as it is a bunch of dominoes crashing down. Now, as long as these things are in the past and stay in the past, it's fine. If you had found out that she had cheated on others, or done things that could perhaps be detrimental to your relationship with her, I would get worried. Otherwise, it is in the past and as the poster above me said you will have to forgive her, IF....

The if here is if she is important enough to you. If you really love her, and she is the girl of your dreams as you say, then you two need to work this out together. It starts with you forgiving her for her past. Maybe even sitting down and both of you having a talk about the past and how you feel about each other in the PRESENT. I wouldn't rule out couple's therapy, as I have heard (though never been) that it can really help a relationship. Or, of course, help end a relationship if the two in the counseling realize that they aren't meant to be.

Are you wrong for feeling upset? No. Are you wrong for feeling a little insecure? No. Are you wrong if you decide to stay with her and then hold it against her? Yes. Make sure that doesn't happen. If this is something you can't deal with, then you need to move on to someone with less "baggage", if you will. Be aware though, at your age it would be very difficult to find someone who has not been in the types of situations she has. Most people that age are going to have been in many relationships and intimate relationships at that. Still, with that being said, just make sure you only keep this going if you both still want it and it isn't going to come between you. Otherwise, it isn't a good idea as it will just be Hell from here on out.

I wish you all the best and hope I was able to help in some way. Take care.
