Hi, I would appreciate your opinion on my situation. For a bit I've been plating two girls, then decided to start an LTR with one of them and ceased contact with the second one. Recently my girlfriend found out about the existence of the other girl, started asking questions, I told the truth about her but I hid the fact I was meeting them simultaneously. I am sure this would end the relationship as she is a really conservative type in that matter. Accuse me of onetis, but I am really committed to continuing the relationship as I believe she is a keeper and I do not want to cheat on that girl myself. For sure she is really committed as well. We never agreed on exclusivity before we actually agreed on the terms for LTR, but of course in her view the "relationship" started way earlier. I feel really bad for hiding the truth and somehow I think waiting for a right moment to tell her is the best solution.

This may raise a more general question about how to handle the topic of plating girls when a transition to LTR occurs. Has anyone been in a similar situation?
Thanks in advance.
