Lesbian Relationship Challenges Support Group
This community is for those who are in a gay marriage, and the unique challenges that may be had in a same-sex relationship. Find support and talk to others in a same-sex marriage, and get advice from the experiences of other members.
First off, you mentioned she had to borrow your bank card so that she could buy game time for this woman. Having been a gamer, I know for sure that you don't spend for another person who is from another country unless there's some form of attachment, which I seem to notice is present based on their Skype exchanges.
Speaking of their Skype exchanges, I can't help but wonder why she only calls this woman when you are already in bed. Personally, I think this is a red flag since why would she do this behind your back if she only sees the other woman as a friend and nothing more?
I would advice you to end your silence, and try to ask her to sit down and have a serious talk with what is really going on. Try a different approach, one that would not lead her to get angry. Maybe instead of asking her right away about this woman, try telling her about what you feel and that you're just telling her to let her know. If she cares about you, she'll figure out on her own that she might already be hurting you and try to make improvements on the situation herself. However, if she still gets angry at you, then I'm sorry to say but no one deserves that kind of treatment. Also, as her gf, she should be more focused on spending time with you than with her WoW playmate (even than the game itself).
I hope this helps.
