I'm in love with my bestfriend's husband

This is difficult to share but I am in love with my best friend’s husband. He and I have spent time together over the years planning events to surprise my friend. From birthday parties, baby showers, anniversary dinners, we have done our fair share of sneaking around.

We have kissed a few times and we have had sex once... last month. He says that he is happily married and have no intention on leaving his wife and their two children but he also says that he enjoys spending time with me, even if it is a quick phone call.  Now, I can’t stop thinking about him. I call him often and he answers. We have the usual conversations but I want to ask him if he loves me the way I love him. It just feels so right when we are together. I know my best friend will be hurt but I’m tired of putting her feelings above my own.

Dear other woman,

Thank you for your question. This is a triangle I see and from your report, your relationship with your best friend’s husband has crossed the line into an affair. If you have respect for him, your friend and for yourself... and even for the sanctity of marriage, the best thing to do is to leave him alone. Someone wise once shared this with me and I’m still processing it to see if it’s fully true but, here goes. He said, ‘Emotions die when they are not fed.’ I don’t know the true author of that statement but I’ve found throughout the years that when we continue to breathe life into situations and people, we continue to tie our livelihoods around them.Take time away from him. Block his calls. Don’t email him or hang out with him. You will never feel secure in a relationship with a man who left his wife and your best friend and their children to pursue a hot romance because you two decided to have an affair during his marriage. 
Another response I have is to wait. Just hold on everything you are doing with him. Keep your conversations with him above board. From your letter, it seems as though he only wants to play around with you. He already clearly stated that he has no intentions on leaving his wife so I am a little confused about why that response has not been received by you. If you are a Christian woman, I ask you to earnestly pray for direction and for clarity on this situation. Also, you may want to seek therapy as this may be a difficult loss to overcome (both losing your friend and your lover) if you do decide to leave your best friend’s husband alone. I wish you the best.
