Why do grown men pull away when they are the ones who came on strong to begin with?

I like DreamWizard's answer.
Also, they sometimes follow their fantasies and not the reality that's clearly in front of them. All genders are guilty of that at times.

Actually, there could be several reasons;

Fear of intimacy. Even the strongest of us have weaknesses, things that we don't want the world to know about. And many men have run into the wrong woman, just as many women have run into the wrong man. This can make either person hesitant about getting "too" close.

Also the closer you get to someone, the more you feel the pain when things start to go wrong.

Lastly, there is a type that only likes the challenge, once they feel it's been met, then they are ready to move on to something else.

I can't speak for all men, only for myself... but they are here and I'm sure they will answer this one. I think this is an excellent question.

There is no such thing as "all men". You can say "Many Men" - you can say "a lot of men" You can most honestly say "All the men I have chosen to be with". But you can't say "All Men" - because it is not true.

Simple logic.

Because for some men they physically they come on strong
but emotionally they back away.
Sort of like the tide...

Afraid of hurting the female.

they thought it would just be fun in the begining but now its real and dangerous... and they aren't taking another real chance right now.

Because they got what they wanted. Guys who come on really strong aren't looking for love -- they're looking for sex.

read ¨why men love *******¨ .... the best read ever for a women.

Men pull away after coming strong because they were never serious to begin with.

It's in their DNA... Some men don't pull away in fact they enjoy helping the woman in there life as they feel good about it. It depends on their childhood and what was hapening. Sounds contrite but true.

i agree with dragoncat.... :)

Hit n' quit

i agree with wiseowl; it's all game.

I want to know how non grown men look like.

wiseowl said it best

sorry if there are men reading this but you its true,men love to chase,once they get what they were chasing,they get bored,sounds stupid i know but thats why they say men are from mars(a dead&barron planet that needs extra help to sustain life)

You probably think this is a man-woman issue when it really isn't.

You just want your feelings to be in synch with someone else when they are not.

You are two separate people whose feelings will be different for most of the time.

That's reality. Deal with it.

it does seem true that in a dating situation if you dont reveal all at first it makes it last longer -- then when he really falls in love with you he's not going anywhere

I think it is in our instinct to run, because we are not about emotions. Love has to be felt from within, and it is hard to express that. I think it maybe too much x chromosome :)
