Help..

Ruby • ttc.
Soo I'm 28 weeks pregnant. Mine and my partners anniversary is coming up on the 28th and I've just bought him maroon 5 concert tickets as an anniversary present. But because of that we won't be able to afford for him to get me anything. And of course I'd rather give him something than get something from him buut I need advice on how to not be resentful over little things like this cause it happens all the time. I put him first and then get upset because he didn't put me first even though when he tries I usually don't let him. I probably sound like an asshole but I genuinely want advice on how to not let little things like this get to me.
