Failed Long Distance Love

So I feel that I will never get over my ex-boyfriend (the one mentioned in my first post). As soon as I feel that I am moving on from him, he calls me or messages me. It is such an extreme of emotions. I feel SUPER excited when he calls and so happy when we speak, but then I rollercoaster down into a pit of depression when we disconnect the call. I just miss him so much and am so angry about our circumstances. I wish that Mexico was treated like Canada and we could go back and forth between the countries with ease. I just do not know how to move on if we keep speaking, but I also do not want to stop speaking with him because I love him. I wish we could be together. I wish he did not need a visa to VISIT that is impossible to get. It is not fair. I wish I could meet someone else sometimes and move on, but until then I will be stuck on him and the good times we shared.
