Thank you. I might as well let this out...

I went on 2 dates with someone, and I'm not sure about us having a connection. Conversation is kind of "on the surface" and our ideals are somewhat different. He randomly showed up at my house with flowers the other day and invited me to go out on Valentine's Day, but I hardly know him just yet. I feel in over my head, and he hardly knows me, but he seems to be really doing a lot of work to pursue things.. Sometimes I start dating when I feel lonely and depressed to seek connection, but my depression gets worse, and it is no longer fun to me. Then, I go back to isolating. I do think aside from that, I'm uncertain about the chemistry. I decided I will give it another chance by going out with him again to give it another shot to get to know him a bit better. But I feel undeserving and kind of guilty over the fact that he seems more into it than I am. I just didn't expect this to happen. Also, I really hate to admit that I don't like when people show up at my house randomly, so although it was super nice of him to give me the flowers, it crosses my boundaries when someone I hardly know does this (he knew where I lived, because he picked me up on the second date). He has been texting throughout the day "good mornings" and some general chit chat and "good nights." He seems very nice, but I still feel a bit awkward when we're together.
I just feel pressure and not sure where to go from this point on.
