What the He!!?!?!?

..is going on in my life? My soon-to-be-ex-husband, who is supposed to be doing a long prison sentence for assaulting my mother (he beat her up, and she's 79 years old, not a very nice thing to do, huh? And all because she had the nerve to tell him he'd had enough to drink!) Well evidently he got some information on somebody in jail & used it to get himself out, because the charges were dropped the other day, for NO good reason that the state could tell her. (Guess he got some information on SOMEBODY in there & turned into a little bitch snitch...which is one thing I never thought he would be!) And now he's calling me constantly & wanting to come by & see me & wanting me to go spend the night with him & all that, WHICH I WON'T!!! (We never had all that much of a sexual click between us anyway--it was more of a drug-buddy thing, ya know? and nowadays I'm straight & planning to stay that way, so there's no point to it, is there?) He has never really turned me on, anymore than any other guy did, nothing especially special there, ya know? (Sometimes there is, and sometimes there isn't, right?. . . ) ANYway, I don't really have any desire to spend any more time with him than I can get out of, for real. I'm pretty angry with him for hitting my mom, still, and don't see why I should inflict his company on myself if I don't have to. However, there is the one thing that draws me to him, and that is SEX!! I mean, I moved to this state 10 years ago, and I have never met anyone here except his friends, etc., ya know? I don't know anybody else, meaning I have none of my old fuck-buddies around to call, and it's getting to a point of desperation for me. . . I NEED!!! Oh God do I need!! I really don't know what to do. . .
