6 month relationship that ultimately failed and I got dumped. Things day to day were great but we had occasional issues come up that what I considered questionable in a committed exclusive relationship. The following incidents caused friction in our relationship. They were patched up but unfortunately accumulated and caused me to lose frame and her attraction. I don't really think my needs were being met either but here is a summary of the events causing friction.

-Accept invitation to attend formal graduation event as a date with long time guy friend while I was away. Did not discuss with partner before accepting invite.

-Close clubs out with single girlfriends early on in the relationship (routinely not just special occasions)

-want to do summer road trip to party with single girlfriends at known equivalent of US spring break

-attend party where an ex was known to be and not invite current boyfriend because to not rub in exs face. Didn't disclose this info until questioned

-careful not to tag or mention anything on social media that would link us together

-go to a remote cabin to drink and celebrate university grad class with strangers including lots of guys. No partners allowed. I didn't know anyone of them or get invited.

-have one word answers if any at all to most above conversations

**other facts: this girl is very attractive with a massive social circle.

My question is are these incidents major red flags, or more like immature and unthoughtful decisions. Or am I wrong to take issue with them.. And if so what incidents in particular are more serious and which ones are me overreacting.

Thanks for everyone's perspective. In summary I feel like she wanted something more casual than I did, even though we were still committed. How many guys would put up with this, even if she's super hot.

TL;DR Hot girlfriend had lots of incidents that tested boundaries of what I thought was acceptable.
