<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I've been with my girlfriend for about three months and things couldn't be better. We spend just about every day together and she makes me happier than I've ever been. She is my first "serious" relationship you could say. I don't really have much relationship experience but she was in a relationship for about three years which ended about five or six months ago. So what my problem is that I think that I love her. And because I'm young and inexperienced it could just be that first relationship sort of thing where you just fall head over heels for the first girl to treat you nice. But I just really care about her deeply. I'm not sure if it's too early or something. So as sort of a reference I was wondering how long into the relationship with your SO did you confess your love? Maybe I need to give things a little more time. I'm not sure.
<bot>: Unsure about the love that I feel for my girlfriend. Also, wondering about how long into the relationship with your SO did you confess your love?
