So true, incredibly honest, and refreshing. I completely agree.Kpt._Rob said:-Snip-
At most, the best we can offer is points to consider before making a decision. On the simplest level, a list of pros and cons to staying in the relationship. But if that doesn't get you anywhere, try to take the entire situation into consideration.
Consider the facts. You had to leave for curfew, straight-up told her that you didn't want her getting drunk out of worry, but she ignored that and stayed. She got drunk, and did just the thing that everyone avoids getting drunk for - cheated. How do you feel about this lack of responsibility and respect? For herself, and for your relationship. Consider how you feel. Do you think this is something you can get past? Can you honestly forgive her? Just how much do you care for her? Did you see a long-term future with her? If so, do you still see the same future, or feel that it's even a possibility? How does she feel about the situation? How honest was the conversation the two of you had? Were you completely honest about how you felt, or did you hold back because she was emotional? Was she even?
There's absolutely no way any of us can tell you what your best choice is. This is something you need to consider yourself, and then make your own decision. Best of luck, I'm sure you'll make a decision that's best for you, even if it doesn't seem like it initially. If you realize that you didn't make the right decision at first, you'll have the chance to make it right then. Life's tough, full of confusing situations and impossible decisions, but you'll make it step by step, day by day. For all those overwhelming situations, take a moment to breathe, consider the facts and possibilities, and relax. You don't need to rush into anything, and it's never the end-all-be-all.
