<human>: (First post on here) My SO other (22) and I (20) have been off and on for about five years. I love him all of my heart, he is my best friend, and I know he loves me as well just by his actions (at least I thought I did)
We've been through good times, and bad, like most couples. The other night we were at Applebees with a friend and the conversation went south... He said that he was "confused" and every girl he hangs out with, he has different feelings for, which makes him question "What love really is" This hurt my feelings because he is always saying that he loves me, but if he doesn't know what it means, or is questioning it, why does he say it?
Anyway, the NEXT day he told me that he loved me and tried to kiss me. I pulled away and told him that he has a lot of things to think about and fast.
He has also came out and said that he feels "stuck" because he is living with me at the moment, and doesn't want to get kicked out(because he would have nowhere to go)
I can sense he might just be trying to wait it out until he moves out, but on the other hand I can see that he truly does care for me. I just don't know if he atm is ONLY using me for shelter (until he moves out on his own) He's also said that when he does move out, it is "free game" What does this mean? My biological clock is clicking, and I do want a family. What should I do? Help.

Give me the gist of the text in a nutshell
<bot>: SO of 5 years is confused and not sure if "loves" me and is living with me, not sure what to do about current situation.
