Should I tell him the reasons why I have major trust issues?

You're still suffering from the rape and need help. If he really cared for you, he wouldn't give you such a difficult time but would try to understand you. The rape isn't really any of his business but you could tell him you have many serious personal problems. Tell him he could either be supportive of you or leave you alone. In any case, you need to seek and get yourself some help. There are many free programs to help rape victims. The rape will continue to haunt you until you get yourself some help. Please get yourself some help.

Pointing out the obvious here - you didn't ask a "yes or no" question so you wouldn't understand the answer if someone just said "yes" or "no".

If your relationship with your guy is good and is not being affected by the past, you can do whatever you want with your memories. It could make you closer by telling him, but if you don't want him to know, don't tell him.

As for worrying about things, all girls do that, just for different reasons.

I would say no. You're vulnerable right now and the past is your own business that has nothing to do with him. When he knows all this about you, he could take advantage of this information and possibly use it against you if you break up. I've trust issues too but telling your whole life story won't fix it. Trust needs to be earned, not just given.

Just communicate and tell him your feelings in the relationship. If you're angry, then don't pretend you're ok etc. (well within reason lol) That kind of thing. Do you tend to go hot and cold because you want to trust someone but then you're not quite sure so you go cold again?Take things slowly in the relationship-dont rush into anything so that you know what you're doing and this will help build trust.

I think you should see a therapist. I have a bad relationship with my father and long story short this has affected my relationships. Everyone has some baggage, that's ok. But personally I wouldn't want to tell someone about something I struggle myself to deal with which obviously says its a touchy subject for me still. But the therapy will definitely help you. When I went, it was great to learn that what I was feeling was understandable and to be expected given everything in my past and present. You need to talk to someone but a professional. Friends, boyfriends and family always think they can deal with these things but I just don't think they can. They mean well but a lot of things are out of the depth of an ordinary person.
