<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm really looking for some insight to my relationship from people that don't know us. So, thank you so much in advance for reading.

I'm 23, my husband is 25. We got married in July 2010. We'd been dating since October 2006 (my freshman/his junior year of college). We met on campus and once we met, we were pretty much inseparable. 

We lived together (officially) for a year before our marriage. All was well. Even things were well after our wedding, until September. When I found out he had been cheating on me for a few months (as in, he pretty much started seeing someone else a month after we got married). When I found out I demanded he quit it, and he did (as far as I know). 

And things have been rough since then - for over a year - for a few reasons. 1) I'm realizing I really don't think I can forgive him. I was molested by a teacher in middle school and I have a lot of trust issues stemming from that, especially in the realm of men/relationships, and whenever husband and I get into an argument I feel like I'm always saying, "well, you shouldn't have cheated on me!"; 2) He's a high school teacher and in grad school part-time, and we don't have a lot of free-time together; 3) I'm falling for someone else.

Before you call out double standard - nothing has moved forward in the relationship with the dude I have a crush on. I just...have a huge crush on him. He doesn't know. I want to tell him but I don't think I can, for obvious (and not-so-obvious) reasons. 

ANYWAY. Any insight is appreciated. This is a very watered-down version of the last five years of my life, but...I'm generally feeling really lost. I can't stop thinking about dude #2 and I really don't know how I feel about moving forward in my marriage with my husband. We aren't anywhere near the point where we can have kids and buy a home, etc, but...I don't know if I want that with him anymore.
<bot>: I got married young, the husband cheated on me, can I forgive him? Probably not. Also I like another dude.
