Can anyone relate??? Need HELP!!!

Okay so I recently dyed my hair. It began to break off due to chemical damage so I cut it. I hated the style when my hair was in its natural state so I constantly put heat into it. Now i have chemical and heat damage and it's getting worse. I want to just do a big chop and start over. But, my boyfriend of 3 years doesn't want me to. I know he wouldn't break up with me if I did but he has begged me numerous times not to. Should I cut it before it gets damaged and risk him not being attracted to me?? Or should I keep it and hope for the best to make him happy??

Current state of my hair
