cannot. you must cut ties immediately to make it finally and gain closure. slowly pulling away will only hurt you more.
you are conflicted. first decide to stay, or go, but no in between. be true to yourself and do what is right in your heart. remember: you are a child of this universe, you belong here, and you have a right to be happy. strive to be happy.
back away...quietly and end communications altogether
just be honest with him. The only way i got out of the very same situation was bite the bullet and do it. I was friends with this *** hole for 6 years and eventually i just told him "look, We had alot of great times and alot of great memories, but in the end i cant continue this relationship (insert reason here). Im sorry." And after that what every they say does not matter. It wont make a single difference. Just end it
what makes your relation ship unhealthy?
