Stuck between what's good for me, and what's good for everyone else.

Im stuck in a very bad situation due to my bad life decisions. Im in a relationship with a girl I really care for, we've been together for a year now. She's the most loyal person ever and would do anything for me. However she has many different idea of what she wants in the future that don't quite match what I want. She wants kids soon, and doesn't want to enjoy being independent. She is also not sexually active and wants to wait for marriage before starting it with me. I on the other hand don't really want that, for I am more materialistic and want to live my life without restrictions. So I unfaithfully met another girl on Tinder, and went on a date with her without telling my girlfriend. This new girl is much more like me and has much more similar viewpoints as me. Including not wanting children until I've seen the world and experienced life. As well as many other things we have in common. I am at such a dilemma for I feel like I owe it to my current girlfriend to stay with her like I said I would, and not break her poor heart. But at the same time I don't want to throw my life away because of a decision I made when I was young. I really need some input for I have no one to talk to about this stuff. Please help me out.

Hey, Do you not think it would hurt her if she knew you joined tinder and went in a date with some else? Some damage has already potentially been done if she found out. It sounds like you’re on different pages as to what you want. And I think if you stayed with her going on more dates with other women will become more and more appealing . If you haven’t deleted your tinder account? Be honest and Talk to her to her.

You've been on a date with another girl. It means you've already broken up with your current girlfriend, she just doesn't know it yet. It's time to be honest and tell exactly everything you wrote here. At the very least hear her point of view about what she wants now. But if she has respect for herself she will likely dump you after hearing what you did anyway.
