Hi, the best way to deal with common roommate problems is not to have them.I overstand where you're coming from with this.First of all...you both have to communicate on waht it is you expect and, what it is you won't tolerate.(feel me?)Most of the time peoples' personalities clash once they've become "comfortable" around thier roommate.Selfishness plays a big role in roommate woes.One does'nt want the other to touch thier food that they bought or,they don't like the company that the other one keeps.The main thing is the bills...Honey, as long as the bills and the rent is paid on time all that other crap is childish and irrelevant to both of your survival and,well being. Learn to compromise and communicate with one another.Just cuz people pay rent doe'nt mean they're grown! (feel me?)Stay encouraged and never forget to pray.God bless You!
