they guy is taking advantage of you.....you see it, yet do nothing...there are many good men out there...finding one is kinda hard with a low self image, you are worth way more, tell yourself that every day till you come to beleive it...he wont pay now..he wont pay ever...and sex should be fun, not something that makes you mad....there are really good men out there......but you got to kiss some frogs i guess to find the prince...good luck.
