Hmmm, wrong section for me. But if its the 3rd time already and its clearly not working out, then I think it'd be best to consider parting ways. Should really consider ways to make the relationship go on though, unless he clearly doesn't care at all.

Sometimes the other might be hurt too, just that you can't see it. So don't always jump to conclusions. You would have to decide for yourself if you will still get hurt or not if you stayed, since no one knows the situation you are in. And sometimes a little compromise is needed to keep the relationship going. Just consider the decisions with a clear mind, like: have you been together for a long time? Then you might want to work things out. Is he doing anything to keep the relationship going? If not, then it would obviously be best to part ways. An unwilling partner = bad relationship.

If in the case that you do decide to part ways, then be warned that the beginning can be a little hard. But with some perseverence and support from friends/families, you'll be back on track again ^^.

Hope this helps! Good luck!
