Is it usual for a couple to breakup twice in 3 months and get back together?

Usual is always very much an 'in the eye of the beholder' thing. I think you can see usual in a 'does it happen to other people' thing and i think yes that does. I think for every individual couple though this is different, what was the reason for the breakup, are they still legit? Or is it a fight gone wrong? Is there good communications after fighting?

You obviously have a lot of chemistry between you but something keeps getting in the way. Maybe a silly argument? Maybe commitment fears? The main thing is you both seem to want to be together and whatever it is that breaks you up it’s time to face it and work through it together. Rather than breaking up you could find time to talk to each other and try to find a balance/solution to your problems between you. Chemistry is great but every relationship takes work and understanding to see them through their differences and become a long term couple

I wouldn’t say it’s completely unusual, but from what I know those relationships are usually toxic and aren’t good for mental health. Those are what most people call off and on relationships and can be untrusting and of course very unstable. If you feel as though it’s not a toxic relationship and no one is getting hurt and you guys just need time apart from each other for a bit I personally don’t see a problem with that. But if you’re concerned or worried about it talk with someone you’re close to our someone you trust so you can hopefully get some advice in your best interest.
