If you can go back and read your own post and not see the problem you are truly ignoring reality.
Clearly, just from what you say, this man is a user, at least with you he is. You talked about paying his phone bill, over $200.00, and then when you wised up and quit giving him money he tells you his phone is cut off. You may be right about what you say but it is also a good bet that it was shut off because he couldn't pay for it. And I would have to ask how he would run up such a bill. That is a lot of talking. How many other women could he talking with?
Most importantly, you have left out the most important person in this on and off again love affair.
"Your Husband". I have been him before and I can tell you sooner or later he will find this out and there is no better way to hurt him than this. I do not know your relationship with your husband but he may think if far better than it really is. You want to loose him forever, keep this up. I divorced my wife of 39 years and moved on. I am married...she lives alone. Mr. wonderful was not so wonderful after all.
You love this man only because you can't have him. If all of a sudden he changed and was with you every moment he could be and became in effect your second husband your feeling for him would change, much like it has for your husband.
You are chasing a rainbow and I can tell you if you ever find that pot of gold it will not be like you thought of it. At the very least do not continue to be his doormat. If you can't do that at least consider giving your husband a divorce.
