My girlfriend has become extremely into running over the past year. I take an interest and ask questions, I'm happy she found something she enjoys.

I work in trades and play sports 2 times a week and go to the gym 3 times a week.

Im always physically tired and feel like a don't get enough rest. My girlfriend asks me to come for runs after I get back from work but I always turn her down because i need to recover.

She has started to become upset because I keep turning her down. She says I need to start taking interest in her stuff. Her new running friends all have boyfriends who are into it as well and I think she wishes she has a partner who would join her.

AITAH?
