I AM IN A RELATIONSHIP FROM PAST 3 YEARS.SHE IS HINDU AND ELDER THAN ME,I M MUSLIMS.
Hi. Thank you for reaching out. If I understand you correctly, you are in a relationship with someone you care about, but because you both fight (argue?) a lot and you do not see any future in the relationship, you would like to end it... You find this difficult because she keeps calling and you don't like being alone without her.
I am not sure whether you have had a conversation with her telling her these things. Have you actually 'broken up' with her? When you say you stay away and try to avoid her, is this after you have told her you don't want to see her any more?
Either way it sounds like you want to break up and move on. I wonder whether you can sit her down and tell her that you do not see a future with her and tell her it is over. Perhaps write a letter to make it clear. It is never easy to break up, but the more clear you can be the best it is in the long run. Perhaps tell her that you both need to rebuild your lives again and think it's best to not have contact with one another. I hope this helps.
