He loves socialising. Likes to be busy and with others all the time.
I like people and enjoy socialising, but I have to work at it and need down time away from crowds.
I'm more than happy for BF to go anywhere, with anyone without me, and happy to be left with a day or evening to myself.
He always wants to persuade me to go. It's not that I don't want to go, don't like the people or won't enjoy it once I'm there, it's that I don't always want to be "out".
He does the same on the rare occasion I've planned to do something by myself or with my own friends, will try and persuade me he should join me.
I don't think it's that he's being controlling, if I put my foot down and insist, he'll accept it without any moaning/sulking/temper. I don't feel unable to say I don't want to go, he just makes it clear he"d prefer it if I did. I think he just genuinely does believe the more the merrier, and that I'll be missing out if I don't go.
To be clear, I love that he's so sociable and the way that opens the world up for an introvert, I just need a break sometimes.
Is there a way to explain it that an extrovert might understand?
