Resisting and Urges of Sexual temptation?

A little back ground info. My boyfriend and I have been together for several years now. The last year of it was long distance.It might can be said that there are "types" that cheat.And my boyfriend was never that type.From the beginning we agreed that it would not be tolerated.He,who has been cheated on before even emphasized how it is the worst thing you can do in a relationship.Well, to my very shocking and devastating surprise, he did. He told me everything.I knew something bad was about to happen because he bagan shaking and crying really bad when started to tell me. He said that all he could think about was wanting to feel something.Nothing else.Immediately my questions became pouring out.Just a bunch of why's and how's.But he kept repeating himself.no one or no thing was in his head other than what he wanted to feel.He said all he could think of was ways that would do this for him.He admitted that they were selfish disgusting thoughts.He said he convinced himself it was nothing more than a feeling so it wasnt wrong until he believed himself.He knew of a girl that would give him oral.And told her bluntly thats what he wanted.(sorry is this is crude).He then told me that he just kept telling himself not to look at her because then he wouldnt have to remember.He said kissing,touching,and sex never crossed his mind because that would mean emotions were involved and he wanted to assure me there were none.I DONT UNDERSTAND.I have never seen him cry like this and I think its partially because of his own guilt and for hurting me.he also cried out that he has a problem and needs counseling.To me, when it comes to cheating..knowing the fact that I love my boyfriend and just that I know its wrong is enough to put any thought of being unfaithful out of my head.I feel that love should be enough for anyone to just be able to say no.or resist the temptation that is put in front of you or that your mind creates. Am i being close minded? I do not know if we will continue to be together.Its no doubt that I love him, but I have self respect.I do not see how some one can say they love someone and still do this,and if they are worth giving a second chance.The main point to this was, is this a real problem that he says he has or just bologna?He really wants "help".He seems very sincere, but he still CHOSE to screw up..
