Why do you need a therapist just to live your life?
You are attracted to what you like why is that a bad thing you are going to hell over?
250 for a guy is not huge if he is tall.
Somebody has fed you some bad advice and IMO you really don't have some extreme fetish.
Liking something is not the same as a fetish.
I'm fat and like fat guys I don't have any fetishes and I am here.
Personally I don't think you are messed up at all. You just have a preference in the kind of guys you like nothing more than that.

I think you are over thinking all of this and trying to find a way to punish yourself for liking fat guys because you don't think you are supposed to be attracted to them.
Wake up GF if you are attracted to bigger guys its OK trust me you aren't going to hell over it.
God made you who you are right?
If God made you attracted to fat guys why argue with him over it?

One tip for you is don't read too much into it.
Just because she catted with you doesn't mean she is "the one".

Bad grammar and spelling drive me crazy but I keep my mouth shut so not to offend the spelling challenged people.

I have been 100 lbs heavier so no I don't think I would

I made a booth at an Arby's groan loudly once.
A GF of mine was in the booth and she is a big girl too so we figured there was close to 800 lbs on the bench so I moved to the other side.
Safety first you know.

Not really I was wearing a skirt at the time.
Leggings or shorts would have been better.

I sunk the legs in soft dirt a few times too. One of my GFs was laughing as I went sinking down.
Her hubby had to lift me back up. Good thing he was a big boy and really strong LOL

I recommend La-Z-boy recliners too

LOL I wasted my money on the chair so that part wasn't so good.

I was always attracted to fat boys in high school.
They were usually a lot nicer boys and more fun to be around.
Lots of girls liked the football players but I never cared for their big egos.
