So I have a complicated situation that I am looking for advise on. This is a little bit of a long story but please bear in there. So I dated this girl for 8 years. Over that time we became best friends. We did everything together, we told each other everything, etc. You pretty much get the picture. We ended up breaking up about a year ago but right before we ended up breaking up, we purchased a home together. In retrospect, probably not the greatest idea but I digress. Since then we have both moved on to other relationships. I have been in a relationship for almost four months and she has bounced around from old friends but nothing serious until now. As of about six months ago, she has started to see my ex best friend. Long story short, we were best friends and then I realized I was being taken advantage of. It was not a financial taking advantage of, but more so a "I did everything" sort of friendship. I had invited him to events, like my birthday parties, we would wait for hours, and then he would not show. We lived down the street, he would never visit, it would have to be me, if he ever needed anything I would be there but not vise versa. Anyway, I introduced him to my ex-girlfriend a number of years ago and then poof, now they are kinda seeing eachother. The funny part is that after I broke up with my ex this "friend" said that I was a sucker because I own the house and let her live there. Then he proceed to call my ex a number of names that I feel should not be repeated. I defended her, and after the conversation he just gave me attitude. Shortly after this we stopped talking, because I saw the "light" of his true ways. Now the problem I feel here is that he feels it is okay to hookup with my ex-girlfriend without even approaching me on the issue. I mean, we do not have to be friends, but I think a common courtesy would be in order. Maybe I am just different, but I could never imagine doing something like this. Furthermore, I feel that he might be doing this to be a bit vindictive but my ex will not hear it. Now as a result of our disagreements on these issues, my ex and I are fighting all the time because I feel like she is choosing this douche over our friendship. He consistantly gets her hopes up and then disappears. He will not even come to see her for crying out loud. To make matters worse we live together so a fight really almost never ends and I am afraid to loose my good friend. I know many are going to say I am still in love with my ex, but that could not be further from the truth. Although I still love her, I am no longer in love with her because I understand that we can no longer be together and can only remain as friends but I am finding this very difficult. So my question to you gus is what should I do in this situation? I have already come up with a few ideas but I would like to hear other views. Just for reference, there are a few issues that do not allow the obvious solutions. - The property that I purchased has since lost about 10% of value plus I would need to put in about another 10% to get the property up to selling potential. So a huge financial loss would be taken to say the least. - I can not short sale the property because then I can not purchase another property for 3 years. I do not feel it is fair to rent something and move out to pay for two properties, etc. - The property is only in my name so any damage would only be done to my credit. What are your thoughts??? I need a viable solution because if I do not reach one soon, I think I might die from the stress. Please help.
