How to get over a bad relationship

Heart broken is a painful thing that every girl or guy on this planet have gone through. I myself have had a lot of heartbroken relationships but I'm still alive and happy.I remember my first most painful relationship was when my cousin's in-law try to steal my boyfriend on my cousin's wedding. I regretted ever attending that wedding with my boyfriend. I resented that in-law so much that I stop my relationship with my cousin and her entire family because they have insulted me and hurt me too much and refused to back up when I ask them to. I remember my boyfriend was tall, light skin and handsome with a college degree everything that a girl would want. I was lucky to be with him or so I thought but after I think for awhile I don't think that he's worth any of my tears.

How it happened was one of my cousin in-law try to hang around my boyfriend the whole day. She then ask for his phone number and try to call him all the time. She wouldn't get away from him at the wedding for a period of 6-7 hours. She was a new comer from another country and I guess she was desperate to find a sugar daddy or something like that. I was very angry and hurt and ask her to stop calling my boyfriend. The thing that made me cut my relationship with them forever is that she refused to and told me that she won't stop calling him. She says she wanted to be his friend. I said there are thousands of single guys at that wedding you don't have to pick my boyfriend unless you're intentionally trying to screw me over. I remember me using very angry language towards her. I was too angry. There was nothing else to do but yells and scream. She never did stop calling him. One day I found out from my friend that he moved away to Texas soon after the wedding. I guess they never had a relationship.

The thing that made me really mad too was my own cousin trying to cover for her in-law and didn't care about my feelings. She told me that she thought that guy was just my friend and not a boyfriend and that's why her in-law try to hit on him. I told her that we were together, you don't have to be blind to see that we're a couple. I'm just polite or just want to keep thing on the low because I hate it when everyone is into my business.
was very heart broken and cry and cut and burned all of my cousin's wedding photos. I sworn that they will never be my relative again. That remained true, I haven't spoke to them for five years. was very hurt and feel very embarassed and insulted at the same time by my relatives. I soon recovered and move on with my life because I thought to myself if things aren't meant to be they won't. So I stop thinking about that situation and try to move on to another guy. I think that it's best not to bring your boyfriend around other women because men are horrible at controlling themselves. There are few of them that would told the other girl to leave him alone.
