Jaded i'm really proud of you! Even though your scared you made a list on your own, you have decided you do want to talk to him and that's really great. Sometimes when i faced with a decision i do a pro's and con's list, but actually it's a cost benefit analysis. I break it into what am i losing by being in this relationship (self worth, happyness etc) and what am i gaining by being in this relationship (companionship..even if it's crappy at least i am not alone, the facade of a "happy" life etc.
Once you see it down on paper you can really see that most likely the costs are just not worth it, it may give you the little extra push to have the conversation with him. Regardless of what you decide you can always count on us to be here for support. I know it's not the same as having the support of your husband or family...but i feel it's a pretty good alternative. Good luck
