Hi Liz, if you wont mind, I want to also post my reply to your thread
Sad to say but the reality could be that you are a convenience to the guy

Think if he really really wanted to leave his wife he would have done that a long time ago. At this stage he doesnt see it neccesary to leave her anymore, because he got a nice time both sides. I know this hits a woman very hard, to feel used, cause I was in the same situation once before. Truth is that some men (woman also maybe) but mostly men can live years loving more than one women. I would suggest, hard as it may be, break up with him, cause, think real hard: If he should leave his wife and move in with you, would you "Ever" be able to trust him again, or would he trust you? The thought of what you guys did for the past 1.5 years would always stay in the back of your head. Also: If he should move in with you, is this reeeeaaaaaally the man of your heart, is this uncertain way of living what you really want for the rest of your life and is it worth taking the risk, to only be dropped for the next women maybe at the age of 45 or later
If you move this man out of your life, try to get him out of your head, make a huge effort to patch things up with your hubby, just maybe you can also have the great life you deserve
