I have been in a relationship for roughly 4 months with someone from an online dating site, at the beginning we were each messaging other people as well as each other. She met and slept with one other person (and initially denied it), I never met up IRL with anyone and since we made it official neither of us has been in contact with a view to meeting.
However she is in fairly regular text contact with one other person from the site, they have never met up but I know she fancies her, and suspect they would meet if the other woman was less shy. When they first met she did not mention me to her, and only mentioned me after we became official and went on holiday together
Am I being unreasonable in not liking her texting this woman? I feel as they are not real life friends it should be easy. She knows it makes me a little uncomfortable but I'm loathe to ask her to stop as I believe I may be paranoid due to infidelity in past relationships, and I really don't want to bring that baggage into a new (and I think promising) relationship.
