what should i do?

Like its just bad.. get together n broke up 3 times.. in last 4 years.. n been 2 months till last time.. im still hurt n now he wants me back for 4th time... i dont know anymore... cause the hell i went through cause of him.. i really still love him.. but i was happy again n everything was going great n he shows up n makes me cry.. the worse thing is that when i talk to him everything he says sounds so right.. What should i do.. give up n let him hurt me again?.. i just cant fight the feelings i still have..

Even thought you love him you just get hurt so it might be best to stay away from him and see if there is something out there who might be better for you. Love doesn't have to necessarily hurt.

If You go back to him for the fourth time, You'll be writing the same message again on here asking what to do about the fifth.. If he really wanted to be with You he'd stay with You, and You wouldn't be going through this for the fourth time.

Ever heard - no guy is worth your tears and the one who is wont make you cry.
I've been in this place before (a month ago) and even though it may hurt alot to let him go it is best for the long run. He cant just think he can keep breaking up with you and think he can just come back and get with you again whenever he likes. He doesn't sound like he respects you and you can do so much better
And i know how it feels to be so happy, forgotten him and everything going great and then you get a message from him
But the main thing is you were fine without him then and you will be now
Write him off - it's for the best believe me you dont want to keep getting hurt by this guy

Hope i helped

Ty so much.
