Happiest – I am not a therapist, psychiatrist or psychologist, so this is just a layeperson’s opinion, but it sounds like you need support and are feeling rejected by your friend who isn’t able to give it to you now, for whatever reason. Perhaps you should consider joining a support group or confiding in another close friend/relative, or seeing a therapist. You definitely need and deserve support and shouldn’t have to waste emotional energy dealing with the seeming rejection of your friend right now on top of everything else. He absolutely may have his reasons and likely cares very much about you, as aries has pointed out, but you can’t run after him because it will only drain you more.
Also, although of course no one can tell you what to do and certainly no one can judge you or what you’ve been through, perhaps, as aries pointed out, your friend is concerned that although you think your abuser has stopped, you don’t really know that for sure. If this individual did this to others before you, wouldn’t you have wanted them to report him or otherwise stop him in some way before he could do it to you? And in the off-chance that he could or would do this again to someone else, or is doing it now, you are in a unique position of being able to help another innocent victim. I am not in any way judging you or telling you what to do and cannot imagine what you’ve been through and are currently going through, and I can’t imagine how hard it would be to come forward, but just giving you something else to consider.
You must take care of yourself! You have so many people here rooting for you!
