Can men really change? Part of me hopes/part of me can't believe it!

Sure! People can change. You did, didn't you? There has to be a profound reason for someone to change. I seem to recall whining about how losing weight to control my sky rocketing blood pressure and cholesterol level is not going to happen unless hell freezes over and then I found out that the girl of my dream is single again and WHAM! hell froze over! Now I am fit enough to join the frickin' army at 39 years old! Fuckin' ay!

by the sound of it no your husband won't change...

I am not to sure, he can change if he wants to but it seams like he doesn't want to.

The vast majority of the time, guys like that don't change. They accept it as part of who they are and convince themselves "I can't help it, I'm a victim of these urges." And things don't sound good, if he's pulling sh*t like you mentioned.
BUT...I'll say this: Go to him and tell him "Things like you sneaking around messaging girls you don't know make me really nervous. I want you to think about this...if you cheat on me, you're proving you don't care about MY feelings. But think about spending the rest of your life with our daughter not wanting you in her life."

Good luck, put the fear of god in him!

PLEASE freaking tell me... if this guy is such a cad... WHY IN THE BLUE HELL DIDYA MARRY HIM?! Are you serious? Tell me this ain't a joke. I hope you recovered from your massive head injury- and got some sense. He's a cheater, and you believe that he gonna be faithful to you? Dizayum! Hope you answer my comment, post haste, tempis fugit, and all that crap...

Men can change yes. But I don't think your hubby is one of those men.
Why you went and had a kid with him, I don't understand.
Maybe it's true that women just want what other women have.
I feel sorry for that boy, and possibly your girl. Depending on how everything plays out.
I don't mean to be harsh, but look on the bright side, maybe he'll get back with you once he finds another woman to impregnate. He just sounds like that type of guy.

Nope. He can't change. Why did you marry him knowing this? You know you're setting yourself up for a huge fall.

if you trusted him when you married him, you wouldn't be checking up on him. you shouldve never married someone you couldn't trust, whether its your problem with trust (cheaters tend to trust the least) or he really isn't trust-worthy.

Listen to me when I say this: Run! Run as far and as fast as you can to get away from this guy. Don't just stand behind the start line, stunned, waiting for some mysterious signal. The gun has already blasted, ringing echoes of warning into the murky air. This becomes a self-esteem issue, at the root of it. You have to believe that you, and your little girl, deserve much more than this. Consider too, the damage to your daughter of seeing her father, (her only male role model) being consistently sneaky and unfaithful to you over the years. Take a hard glimpse into the future and you will see this derailing her trust in men, and her taste in them.. unfortunately, as well as what she will allow herself to be treated like after watching you accept unfaithfullness in marriage. I speak from experience. This guy is ultimately not going to stop being bad. You need to get away, mourn the death of this bad relationsip however you must, and then open up to the idea of a nice guy, one that is worthy of your time, love and commitment. Good luck!

I'll give you a quote for this one:

"Don't stay because you think "it will get better." You'll be mad at yourself a year later for staying when things are not better. "
