Well, since I've been broken up my ex and I have stayed in contact. Just recently he's been talking about us maybe getting back together. But for now it's just all talk considering he lives with his new girlfriend and he's kind of stuck in that position, my gut tells me he's no good, but my heart tells me we should give it another shot. It's confusing and I think he's leading me on a little bit.

How do I approach the situation!

Listen to your gut, and leave him alone, having nothing else to do with him, and tell your heart to shut the hell up.

Even if he leaves this girl for you, what makes you think he can't go back?

What's crazy is he blows sweet nothings (I do mean NOTHINGS), in your ear, and her too probably.

NO DOUBT, you are both being PLAYED for zip darn fools.

Good for you for thinking this through.

My advice to you is to leave him as an ex. As long as he is involved with another woman, he is not available, even to talk about a relationship with you, or anybody else.

His girlfriend may or may not know that he's trying to stir things up again with you, and likely not aware that you are even in the picture. That is very unfair to her, for you to carry on with her boyfriend.

I would give him one last phone call and tell him, as long as he is involved with anybody else, you won't consider any kind of relationship with him. Then stop all contact with him, and get on with your life.

You too, need to move on and live your life without going backwards, or waiting for him to come around.

Stop talking with him, he is wanting a back up in case his new girl friend falls though, He is not stuck, just being a player.

If you go to the fridge to get milk and you open it up and it smells bad, do you put it back in the fridge and come back a month later to see if it got any better?

As people we seem compelled to lower our standards to meet what's available to us at the time, not the other way around. He's with somebody and he's talking about going back to you. How long till he's with you and talking about going somewhere else?

'ForeverZero' is exact in his words. Your relationship with this man, (who actually sounds 'sour' himself and we all know that 'sour milk doth curdles') reads like a 'game' for him... discard him from your foremind and concentrate on being a happy, single, liberated woman.
Nobody, man or woman, wants/needs to be in a 'relay-shun-ship' in which we are soon to discarded for the 'next best thing'... then only to find out that the 'ex' does not like the colour of the green grass on the other side. Forget him and enjoy YOURself. I wish you the very best of luck in your future.
