<human>: Summarize the given text in a few sentences.

I met my girlfriend as a coworker, she was in a previous relationship that was pushing to almost 5 years. Maybe a little after 2 months we started talking, and hanging out. First it was just friendly but she started to gain an attraction towards me and we ended up dating later down the road. I'm now in my freshman year of college and about an 1 1/2 drive away form her. While she's enrolled in the community college near her home that just so happens to have her ex enrolled in as well. 

I do trust her, but it's the core concept of her being around him so often. I'm not afraid of her leaving me again and going back to that scrub. It's just that my main issue is that her and her ex still make really frequent contact with each other and she'll frequently visit him. I've already addressed this issue with her and made it clear I don't like the scrub nor do I want her to talk to him let alone visit him. I will admit I am a jealous type and don't like it when certan things go my way. I know they've probably had a nice bond in those almost 5 years, but there's a reason you leave things behind you, right?  

Here's where it get's real good, no more than two days after discussing this issue with her, and her promising she wouldn't visit him. She goes over Sunday evening and spends some time with him. I'm texting her probably around 7pm and she texted me and told me she was spending time over there I told her "You have a goodnight" and that was that.
<bot>: My girlfriend still maintains a frequent contact, visit basis with her ex-boyfriend. I don't like it, she knows that and does it anyway. Should I be mad?
