<human>: Can you summarize the given text in a few sentences?

My boyfriend [23] and I [21/f] have been dating for a month. All of that month has been long distance because I am away at college. We were not exclusively dating in the 4 months leading up to me leaving for school, although we did hang out often, go out together, and kiss (but not heavily). He was a huge player back in the day but really wants to settle down now. I've been molested and have a history of abusive men, and I struggle with intimacy and trust. He's been fantastic about not rushing/pressuring me into anything physical. He's very cautious and respectful, which I love about him. 

The fact that he is so careful and comfortable with taking things slowly is exactly why I was surprised when he told me last night that he is in love with me. My past has made it hard for me to fall for people quickly, but that inclination was never really a part of my nature anyway. He is far better than any other man I've dated and he's given me no reason to doubt him. But part of me wonders if him falling so quickly should be a red flag. 

What are your thoughts?
<bot>: My seemingly cautious boyfriend tells me he's in love with me after a month, and I'm concerned it may be a red flag.
