Sorry for your troubles but running away isn't going to help any. Make up your mind whether to stay or leave and then do it. Use professional help in making the decision if you want. Get counseling if you want. BUT save the miles until you've decided. If it is stay, go together someplace and get started over. If it is to go, divorce her (shooting, where quicker and often cheaper, is frowned upon. Once free, use your miles and do a long unwind.

Using them while mad is mostly wasting them although a long weekend to clear your head may prove valuable.

Just a thought. I wasn't there and do not know enough to be sure my advice is correct.

Heal and stay well.
