I Dated A Man In The Past Who Was Very

I dated a man in the past who was very stressed then about me being separated from my husband and couldn't make love to me(not hard enough) ...I thought it was me ...that I wasn't enough for him or he didn't want me...later he left me for another...whom he married and had a baby with...Now some years later he appraoched me again however again he couldn't get an erection for intercourse...I know he is attracted to me but why can't we make out???He said he had many things on his mind and this time we are both married and he has a 2mth baby...but when two people are in bed together don't things just happen anyway??Is it possible he has the same problem with his wife??
