Things have heated up between me and this guy, but like right after we've gotten...indecent, he just shuts down and becomes moody and distant. I give him time to calm down and then we're fine again, but I'm scared to do anything like that with him. I really like him, but that's stressful! I start to feel bad about myself and unwanted and it's horrible. He says it's not me and keeps evading my questions trying to get a serious answer.
