@knowledgeispower123,
I think that you are angry at yourself for 1) picking the wrong man again, 2) not seeing those boundries you set for yourself clear enough when choosing this partner.
Did you think that 43 was old? And, just because you "told" him why your marriage didn't work, that you didn't have to make it clear that if he was to be anything simular you would not stay?
I can only imagine that you snooped one day and found your husband looking at porn. That, you thought you were sexy enough to look at, engaged in enough "sex" so couldn't see why on earth he would want to look at that, let alone the fact that it means "other women" or does it?
Then you googled until your heart was content. It's highly addictive. knowledge is power. So after kicking him to the curb you ensured in your mind you would never, ever, go out with anyone that watched porn.
But like I said, all you did was "tell" this boyfriend what occurred in your marriage and why you left. He may very well have stated it didn't interest him, he may very well have lied. But that was it. That was all you were looking at ensuring wasn't in your life this time. You missed the controlling, the cheating, the dating sites, you missed his character totally. And, so... you entered again into the wrong relationship.
So this time "knowledgeispower" you checked the computer and yep, porn and worse, dating sites, naked photos, probably messages back and forth. And, again, why? He said I was sexy. I don't know it's in his blood? You didn't have enough "intimacy" in loving ways, rather sex... You constantly monitored him to check to make sure he wasn't looking at porn like your ex? You fought over things and didn't have much of a communication line? Or he was just wanting "someone" in his life, settled and so did you and it was a bad match.
What you are missing is this. You think knowledge is power. You will catch them. You have zero trust issues due to your ex-husband, you think that by entering a relationship with zero trust issues you will still succeed providing they don't watch porn. Not so. Trust is the key to any relationship.
You miss, the warning signs and carry on in a dating situation turning it into a relationship that you don't want.
You snoop and google and snoop and google.. which has to eat you alive.
Go and get closure on your past marriage and realise 45 is not old. Set yourself your exact boundries of what you want in life for you and your children. Make things clear of what those boundries are and read the signs, date longer instead of falling into a relationship that's wrong for you and quit snooping, seek help on trust issues and get on with your life.
