My relationship with my boyfriend is falling apart. What do I do? I have no hope.?

Sounds like a relationship I was in a couple years ago. You can't be happy with him and you can't be happy without him either. They know exactley what to so to suck you back in every time. It shows him that he has the upper hand and is in control of the relatioship. What is gonna stop him from going offf again on another one of his cheating binges. He is knows that you will always be there for him to take him back in open arms right?? For me this when on for about 3 years. I was so depressed on our times off. Thought that there was nobody else except him. I about killing myself at times when we were broken up because I thought I could never live without him. One day i just had had enough. I had to do something to get out of the relatioship in order to save my own life. I applied for a job oiut West a tree planter...lol...and I wnet. Had all the arrangements done and was gone within a week. I left for 3 months and got away from things. i will be honest though, I was depressed and missed him the entire time I was out there. When i came home he had a new GF already and that hurt. It laster a few more months and then he asked me back again. i was an idiot and gave in. It wasnt the same though, i felt ashamed and guilty. All the effort I had made to get away for nothing. Thats made me realize i had to end it for good!! That is axactely what I did. It made me realize that time really does heal. Eventually he started texting me and trying to contact me again. This time I had the upper hand and was in control. It felt great abnd gave me the confidence to keep moving on. In time, I got over things and was in a happy state again, never thought it would happen but it did!! I changed my phone number and deleted him for my life completely. That is what you need to do as well. Relationships should never be that hard. You shouldnt have to play games or ever feel depressed like you do. It isnt healthy. My advice to you is to end the relationship for good. You can't change a guy like you may think. It doesnt work that way. In time you will get over him and be happy again. Try reading the book "It's called a breakup because it's Broken". That is an amazing book and it tells you the honest and blunt truth. Trusta me this guy sounds like an *** and isnt worth your time. Could he be bi-polar? Sounds like he is up and down. One day you will meet a guy who is amazing and will treat you right. I know that is what they all say and I didnt beleive either but it's true. I met an amazing guy a year after when I wasn't looking. He was my perfect mold and treats me like a queen. You can find that is you just give it time!! There are nice guys out there and you aren't with one of them. Good luck and I hope you do the right thing.
