<human>: Can you provide a brief overview of the text?

We've been together for about 1.5 yrs.

We've had a few bumps in the road, as she's had trouble saying, "No," to guys that hit on her or flirt with her.  She just takes it as them being nice, and also to avoid causing an awkward situation with people.

Example 1: When a coworker asked her to coffee, she agreed, and explained to me that it was just a friendly gesture.  After two coffee meetings and a lunch, he asked her to a movie, and that's where I drew the line, and she understood what I meant.

Example 2: A guy in her building invited her over for game night with a few of his friends, which has now become a weekly thing.  This progressed to him giving her rides to the grocery store, laundromat, and overall, they've gotten quite close.  One day, he asked her over for dinner, just the two of them, and I drew the line there.

Example 3: Her roommate's boyfriend made a pass at her, along the lines of, "Y'know, if my gf's not home, maybe we can chill together sometime."  She just said, "yeah, sure."  He then said, "I'm so tempted to cheat on my gf with you."  She, again, just laughed it off, not wanting to make things uncomfortable.

Overall, her interactions with other men have not been too...comforting.  Now, whenever she mentions that she ran into so-and-so (a guy), I can feel my heart rate racing, expecting some sort of issue where we have to talk about it.  I'm not sure how to get over this and stop stressing whenever her and another guy go somewhere/talk.  Help?
<bot>: gf's track record of rejecting guys that hit on her have not been too...great.  Now, I get anxious every time she and another guy talk/hang out.  Help?
