Some men do not understand platonic friendships.
Some men like to chase other women.
Its a game.
Some men just go around seeking out affairs all the time, seeing who they can convince to cozy up with. And they use their same stupid line of "I'm married just on paper."
Some men flirt around, but under the currents, they see you as a woman who they want to nab and see if they can convince the woman, to give in.
Does he have children?
The guy, obviously went around searching around for past classmates from childhood that he may have had a crush on. Doing it via FB. You have been FB'ing with him for a year. Now he is getting all romantic on you. And trying to see if you will bite the bait.
Tell him "I wonder how your Wife (or kids) would feel if they knew you were hitting up women from your past?
I bet, if his wife looked up his FaceBook page (unless he has a secret one), she would be flat out hurt/pissed/disgusted with him.
Tell him you will not get caught up in his soap opera flashback to the past wishful thinking. You are an adult.
Tell him, married or not you are NOT interested in him that way, he is just a classmate from childhood.
Some men, do not get... hints, nor LOL's.
Some men think LOL's or laughing, is flirting.
If you tell him you are not interested in him because he is married. Then, WHAT IF one day he gets divorced and then keeps, trying to hook you?
So, from the get go, just tell him, married or single, you are not interested in him. Otherwise, he may contact you again, if he is ever separated or divorced.
And... if you keep communicating with him, remember that he has a crush on you. What man, can separate a crush from platonic feelings?
His poor wife. Being married to a man, who says he is only married on paper.
What deceit.
I wouldn't want a friend like that.
And the thing is, this is probably not the first time, he has done this. ie: trying to hook up with another woman, not his wife.
