Welcome to the HealingWell Depression forum. I am so glad that you joined us.
I say the same, ignore your sister. She is jealous. And jealousy is a nasty thing to go through. She will eventually come around. But you can't let her ruin your relationship. You love this girl. And she loves you. Maybe she could block your sister's calls. I feel badly for her putting up with this upheaval. Jealousy is an nasty monster. And your sister will get over it. So just keep on with your girlfriend and ignore your sister's antics. That is the best that you can do. You can't let your sister run your life.
Best wishes to you.
