<human>: Can you condense the text into three sentences or less?

Should I [23/F] be at all concerned if my bf [22/M] of 5 yrs is "stalking" other women on facebook/twitter/instagram on a daily basis? All of the women are people he has met or seen around his college campus. There are a few women in particular that he keeps tabs on closely, sometimes several times a day. Let's just say, he knows exactly which albums to go to for swimsuit pictures. To my knowledge, he has made no attempt to further contact with these women.

Gentleman...I need to know..is this behavior normal for a guy in a longterm relationship!? I cannot begin to understand what he gets out of doing this..especially since I've been the horny one/one to initiate sex lately. According to his browser history, it should be the other way around. 

Should I look the other way, confront him about it, or consider breaking up with him?
<bot>: My bf of 5 yrs methodically stalks women he knows/knows of on social media sites every damn day. Is this normal/how should I respond to it?
