Tired of the bs

I am so so tired of the bs that comes with this relationship. I love her with everything that I am, but damnit, I don't know how much more I can take. I want to go see my dad today for his birthday, but apparently "gas money" is the issue, well fuck it, I am going anyway-WE HAVE THE GAS MONEY- if I go without her a fight shall come, if I go try to discuss with her my passion for going- a fight, if I don't go or talk to her about it there will be peace in the house... but my dad has sounded so down lately and its his birthday, I missed fathers day with him, but she was there visiting her parents the weekend of fathers day.. what to do what to do.
