I’m 31F and I’ve been dating a younger guy in his mid 20s. So far we’ve gone on 3 dates. Our first date was bowling, second date was at a restaurant , and our last date was the movies. This was all within a week and a half. Yesterday after the movies he suggested we go to his house.I told him I didn’t feel comfortable enough to go over his house. He also lives with his mom and younger sister so I found it disrespectful to bring over a girl you’ve just met. I suggested a walk in the park in which he then agreed to. Is this a red flag already? He’s been extremely affectionate but I’m starting to feel an ick.
