2 very different people

J

My partner and I are very different people which is starting to cause issues already and it's only been a month. I'm a private person, I don't like pda and being affectionate infront of others including my friends and family whereas my partner is the opposite, he's outgoing and in constant need of affection. I've been pushing myself from the very start to be more like him, I hold his hand in public, play fight with him and when we went to a concert I didn't complain about him wrapping his arms around me from behind even though I HATE it. Yet the other day he said my distance makes him feel like I'm embarrassed by him and that I don't want it to seem like a relationship. I find it difficult to communicate my issues in relationships which is the cause of all my break ups but I'd like to try to work through this because he's nice to me.
