It's not so much about if men/women suck. Even the nicest people can do nasty things sometimes. It's about pain and how it's dealt with.
Pretty much go along with salts post. So many things start with "love you". Does require a bit of work though.
GutLovingGirl, your post almost bought a tear to this old bugger. Getting bad news about ones health is huge, who knows what buttons that presses, no doubt your anxiety must be all over the place.
Hearing things like, "i'm never enough for anyone", "allow myself to be happy and trusting", "maybe i'm just not enough for anyone", etc. Damn, I can't even express how sad those thoughts makes me feel, even though I know they are feelings that many have at some stage. Not easy.
How about turning things around.
Don't let a man "get me into bed". If you choose, you take him to bed. Now if you want, the next morning, kick him out of bed, no kiss no cuddle, show him the door. You can give him a few minutes to get dressed, or just chuck his clothes out the door.
Ok perhaps not the best suggestion, but the point is to try and change the patterns that bring you pain.
