<human>: Can you summarize the given text in a few sentences?

So I just really need a neutral opinion on this, and I need to be bluntly told if I'm being a pathetic idiot.

So my boyfriend of more than two years is a very outgoing and flirty (although he claims he doesn't realize it) person. I think his friendliness and talkative personality is great, especially since I'm so introverted and not very social. However, sometimes I'm uncomfortable with how he talks to women- he tends to get a bit too personal and flirtatious for my comfort.  

I've brought up that the fact that he only reaches out to girls bothers me, but he says he's just always gotten along with girls better. We've had problems in the past with his ex still texting him after several years (still not sure if she was just crazy or if he was encouraging it) and with another girl who admitted she loved him texting him all the time. But nothing has really changed.

So yesterday, I was borrowing his phone and his facebook was up. I looked at his messages out of curiosity, not planning on reading anything, and I saw messages from several girls, including a girl that I've always had a weird gut feeling that he liked. This is the only girl I've actually sat him down and seriously asked him about, but he just said he barely knew her and just wanted to be friends with her.

So I opened these messages and saw that he had started them, saying something like "I really enjoy seeing you around." He then asked about school (they had a class together last semester), and then he said "maybe I'll see you around more and we can get a coffee together."

I basically freaked out and told him I was having too hard of a time trusting him and that I couldn't date him anymore. Was this stupid? He says he was never going to follow up on it and he just wanted to make friends, and I can see how asking to coffee could just be a friendly invitation. I kind of want to break up, but we have nonrefundable tickets for a week-long vacation in a few weeks and I don't know what to do. Be as harsh as you want.
<bot>: My boyfriend is too flirty with other women for my comfort sometimes. Not sure if he asked this girl on a date, not sure if I'm being an insecure jealous freak.
