Why do I still Love him, dream about the other and marry this one...

And this to shall pass...My thoughts that exhale memories of lovers that Ive experienced. Let me ask the question is it an issue to always love some one but you know being with them isn't healthy. Then on another note why the hell you thinking about being with one guy when you still dreaming about another and fucking the current one. This shit is confusing. Need help in letting the past rest. At the same time I'm over wanting to still have relations with one of the past experiences. Now there is one that came out of the wood works and I think about how good his head was but him I never loved he was just a lover that passed through. There is a recent ex lover who I'm trying to remove from my list of wanting to be held by him one last time. Some body please help this "I just need to kiss him....maybe stick the head in one last time" female out...
