In love with a married man...

I met this handsome and intelligent man on a business trip.  He didn't make a sexual pass at first, so I took him as being a gentleman.  We laughed, ate and drank the whole night we were together.  He treated me like an absolute queen!  Anything I wanted or needed...he provided.  The conversation was so intellectual and enjoying that it felt like there could be more there other than an attraction.   We exchanged telephone numbers and email addresses to keep in touch because it was what we both wanted.  It was great talking to him all the time and getting to know someone on a deeper level than sexual intimacy.  Yes, the urge was there, but I am a lady first and I will wait until it is the right time for me.  I started to develop feeling for him in a short period of time and it felt real...it felt like the beginning stages of love not lust.  About three months into the new relationship, things started to get strange; calling later than normal, not answering my calls as much, talking low on the phone.  That's when I put two and two together...He's married!!  I asked him bluntly and he finally confessed.  When he confessed, he also pulled out the divorced papers...stating that he has been going through a divorce before we met and that I am the woman he wants to be with.  I feel that he is off limits because they are still legally married; and karma will come back to me even worse if I hang on to this married man.  I don't know why he didn't tell me in the beginning...it would've been different.  Why does this always happen to me...meet a great, intelligent, handsome, sexy guy...he's always married!?  He still wants to be with me when his divorce is over, but I'm not sure I want that now.  We still are friends, but the conversation has its limits.  Maybe I'm leading him on by continuing to be his friend...
