How can I choice this? Relocate over my mom or my boyfriend?

I recently learned that my mother is slowly decline in health with lung health.

She works full time and is the only source of income for her household of disabled husband and a teenaged daughter. With nobody help her to take a break or even help her husband to get out of the house.

I, of course, have a heart to help others in need. However, the relationship I have with her had been very rocky terrain.

My boyfriend doesn’t want me to relocate because his biggest fear, the history I had with her. He refused to relocate with me because of his family, but my mother recently relocated 2,000 miles to the west to pursuit my eldest sister out of jealousy since 2013. Since nobody wants to help her...

My boyfriend begged me and said, “I would love to keep you on the dog lease and DON’T YOU DARE! I LOVE YOU!!” We been together for 7 years.

Out of the 4 daughters, I am only one who is willing to help.

Despite the fact my mom and I had a rough history. I forgave her and I want to help, just because I want to help, but it a great deal of distance away from her while in the same state with her.

I am in a very complicated situation that I feel the need to help her but my boyfriend is holding my arm down begging me not to go. What am I supposed to do..?

Job isn’t the issue, I can easily transfer anywhere. But the two- my mom, or my boyfriend of 7 years?
