Asks for a break everytime we argue

Irene 💝
Guys my boyfriend asks for a break everytime we have an argument. Says i remind him of his ex and am no different that al break his heart. Sometimes he says am holding back dont know on what. I love him so much..i dont think i want to let him go. But this is the fourth time and i really dont know if i can do this anymore. Am torn in the middle.
