Like Kerry, it seems to me that saying or not saying "I love you" does not necessarily translate to actually loving or not loving you. There are many ways to express love and the love languages model is probably just a subset of this. It may also be a cultural thing. If he was one to say "I love you" twice a day to you before and he's not doing it now I'd worry. I think its probably quite a struggle now for BOTH of you given his past deception and infidelity. But if the deception and flirting is actually going on you have to get to the bottom of it as soon as possible; this requires being smart thru' the emotional pain which is hard. Why not for now get some on-going help or if feasible tell him how you feel in a non-demanding or indirect way whenever a persistent/strong feeling takes hold of you and see where things go?
