I can’t understand his exact feelings for me.?

You don't want to be a home wrecker.It will mess his daughter up. I know someone who is going through this now.She is a co-worker,and is 23 years old .Has an older brother also.She seems to be doing ok.It is not meant to be between you two.He loves his wife. She finds out it may be over.......He is a friend that is there for you which gives you someone to talk to The other side is . Your at a low point in your life Vulnerable .What are his intentions .Guys are dogs sometimes,and it sounds like he is using you.He said he is crazy for your body . He wants that cause his wife may not have that at her age ,plus your something different for him.Who will pass up someone who is 20 years younger at his age .
