It sounds like your both lacking trust in each other. And falling for another girl is showing cracks in your current relationship, what do you think is missing that maybe spending time with this new girl may be filling out? Once you discover the problem, its best to talk about it next time u see ur gf. Youv not made a move, so try remove things, and only start anything with this new girl if you and your girlfriend feel like you need to go on separate paths. Don't cheat, it would give her reason to believe she was right not to fully trust u. Hope it all works out
