would you choose to fight for the one you love over your relatives?

My opinion is that if you love him then your relatives should be happy for you and be glad that you have found someone that makes you happy, but as sounds that this is not the case. If I was in your shoes I would fight for the one i loved as he is the major part of your life now, and he is in your future that you have planned. (ie you are planning to settle down together.) If your relatives can not learn to accept that you will be staying with him then that is their loss. If you are happy and they cannot see past their differences they have or their opinions of your boyfriend and see this, then to me they are thinking of themselves and not about what you want, or about the things that are important to you. Do not give up on the one you love as if your relaitives truly care about you they will eventually be able to put their own opinions and differences aside if they want to remain in contact with you. I wish you all the best in whatever path you choose.
