Relationships after affair/divorce

I'm losing all hope on guys. I was in a relationship for 10 years, the last 2 we were married. He was having an affair (which, according to him, started when I was going thru depression) and that affair lasted 7 years (do the math). Right now we've been separated for 2 years and going thru divorce. I've become very cynical about relationships and guys. The guys I have met just want to have sex, it's the first thing they want. All the guys I know have cheated on their partners. Every time I see posts about proposals and weddings I smh and roll my eyes. I no longer believe. Will I ever get out of this mode? How did you get out? And please, do not write anything about God, and Him having a plan or saving the right guy for me. That's a separate conversation I'm having with Him.
