I'm Terrified

I think this whole being cheated on thing is affecting me more than I initially thought.  When I first found out I felt physically sick.  I was nauseous, lightheaded, and felt like I was about to jump out of my skin.  Then I was just angry that someone I loved could actually do that to me and not even feel badly about it.  Now that he's gone but still trying to communicate with me on an almost daily basis, it's starting to hurt at a deeper level.

I think I tried not to take it too personally at first, just blaming it on him being an asshole, but of course now I have more quiet time to myself to actually consider and process everything.  Now I'm scared that it's going to affect my future relationships.  If I ever thought I could trust anyone not to cheat it was him, given his history of being cheated on pretty badly in the past.  How do you let go of the fear of being lied to again?  How do you learn to trust?

He let me go on and on about our wedding and talking about our future children.  I went to that freakin bridal fair.  I feel like such an idiot.  But I didn't know.  He's a good liar.

I wish he had just been honest with me from the beginning.  I mean I certainly gave him plenty of opportunities to tell the truth.  I outright asked him, and he chose to lie.  So instead I found out the hard way and felt even more betrayed.  If he had told me way back when it first happened he could have saved me quite a few wasted months.  And a lot of heartache.  I hate being lied to.
