It seems true that you don’t love him enough to have a long term relationship or even continuing it with your current boyfriend. However with that said don’t go right back to your ex either without really considering what you are going through. It seems that after a certain amount of time after a breakup we seem to forget all the reasons why the relationship ended and when the situation presents it self to reclaim lost love we jump all over it. Later we say, “what was I thinking? It is all happening all over again.” I had seen on the television show, “how I met your mother” Ted wrote himself a letter to be given to him by his bestfriend if he was considering getting back with his ex. The situation arose and he was love struck again and his friend gave him the letter that he wrote to himself and sadly I can’t remember exactly what happened I think there was a plot twist, but the lesson is a good one we seem to get relationship amnesia. If you went into your current relationship fast then consider taking a break from relationships, that doesn’t mean you can’t talk with your ex maybe you will remember why it didn’t work before getting back into something with him. Give yourself the break and try dating other guys. There is no reason you should feel you need to rush.
