It’s a red flag for as long as longevity in a relationship goes. If everyone is on board and knows the likely outcome then it just is what it is. Have fun and party ways. But, it sounds like the end goal for her might be to get married and do the “live happily ever after” thing. Then yes it’s a red flag in the sense that she would likely be wasting her time.

This doesn’t mean you’re a bad person, imo. Especially since you let her know your history and each outcome. And, it’s pretty reasonable for her to be hesitant to commit if she knows it’s not likely going to last because you will inevitably get bored.

Just my 2 cents anyway.

I still use hexchat… suppose i shouldn’t since it’s not being updated anymore. But, I’ve tried a bunch and it’s the only one i like.
