<human>: Give me the gist of the text in a nutshell

[throwaway] It's been three years, and we have broken up three times mainly because of issues related to long-distance. Crucially, he was the main instigator all three times, but is now saying he desperately wants to get back together.

I'm cuckoo crazy in love with him, but getting back together a fourth time seems pretty nuts- when is it time to cut and run? I don't want to be the girl who keeps going back to a guy when everyone around her realises that the sink sank a long time ago.

Any stories/advice would be ridiculously useful- to be honest mainly just looking for a bit of objectivity here as most of my friends/family are against me giving it another go (not because he is not a decent guy, but because they don't want to see me get hurt again)...
<bot>: Me [23 F] with my ish-ex [23 M]- how many times can you get back together before you're 'that girl'?
