<human>: Provide a brief overview of the text.

So, my girlfriend and I have been going out for about a month, and I'm not sure how I feel about the relationship. She seems to be smothering me with affection, but I don't feel the same way. I mean, I like her a lot, but I'm not in love with her, but she's way head over heels over me. 

Like, this weekend she wants me to spend the night and meet her family, and I spent a weekend with her before and it was all about sex for her, like she wanted way more than I felt like giving. I was exhausted afterwards and she wanted more. I've never been in a relationship like this, where she was more into it than I was, and I don't know how to respond.

I think I might try and pick up hours at work as an excuse to get out of it, just because I worked 6 days in a row this week and I need some me time. I mean, I don't want to break up with her because it's been years since I had a steady relationship, but I feel like it's physically exhausting and I don't want to spend all this time with her.
<bot>: My girlfriend is smothering me with affection and I don't know how to respond, should I tell her we should take it more slowly or should I tell her how I feel about the whole thing?
