Aloe Plant question

Aloe Plant question

Hi I am not really a gardner...I have no talent in this field at all although my family members seem to have wonderful fun and luck with vegetable gardens. My husband and I have a aloe plant....it was his before we married and although he knows more than I about plants it has somehow fallen on me to worry about this little plant. It began looking a little puny after it was moved to the back bedroom so at mom's suggestion I moved it to the living room near a window. It began to really perk up. But now it is looking a bit sad again and I wonder if it has grown too large for it's pot. I have asked my husband to re-pot it but if he doesn't do it by this weekend then I am going to have do it......the problem is I have no idea at all how or what to do. Could someone please give me some advice.
Ok time for a laugh at harvest time.
