I think spending time with this guy made you wonder what it would be like to be with him. if you’d be happier with him or some else. During a 2 split when your feeling emotional etc I think it’s pretty normal to start to question things. But your thoughts, partially negative ones, aren't always right. Who is to say this guy is any better or a relationship with him would be better then what you have. Couples do fight and have breaks sometimes it improves things sometimes it doesn't
Jumping into a relationship straight away is never a good idea. You need time to yourself after a long relationship to rediscover your self.
I’d weight it out before you do anything only you know if you are truly happy or if you want to stay with bf to try and improve things.
You love each other but you split up for two weeks?
Then you love each other again but you get a crush on another boy and you think about splitting up?
I only know one thing:
You do not love as I do.
I would suggest doing what you want.
If you are unsure about that: picture yourself vividly in 2,12 and 24 months with any decision you might take.
Take the one that's best
So for arguments sake say you choose the new guy. What happens if in another three years you're relationship with him has become safe and stable as is normal. Then you feel butterflies or excitement with a new guy?
You see what I mean?
This could potentially be an endless cycle, or it can end when you decide that one person is so right for you that you wouldn't give them up for anyone else. No matter how you might be temporarily feeling about anyone else.
