Am I selfish for taking myself on vacation alone?

I, 30f, and my husband 35m, have been married for a bit less than a year. We just recently went on our honeymoon, which was absolutely ruined with 3 days of horrible fighting. The tension has continued through today, about a week later.

Usually, my husband and i plan a trip together at least once a year to just get away, reset, etc. However, I feel worse than before we even went. Obviously theres a ton more that goes into this but without going into details:

Am i just a complete selfish B if I went on a long weekend to somewhere secluded to just decompress? I would be paying for it all with my own money too.
