My boyfriend has agoraphobia and I’m so frustrated and starting to resent him

I love him to death and I support him and I’m just so tired. I’m so sick of never getting to go anywhere because he doesn’t like to leave the house. We’re both 22 and I just want to go on adventures and have fun and I never get to. He never even leaves to go grocery shopping. It’s all me and I’m okay with that, but I just wish he’d put effort into going out to fun things even if it’s scary. I want to go to the beach and to the parks and just have fun. I’m so tired of never getting to leave the house. I’m not upset that he’s like this, it’s not his fault. I’m just so tired. He’s been like this since high school. Has anyone else dealt with this? What did you do??
