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

There used to be 5 of us living in a 3-br apartment. All of the rooms are really big, so it's totally reasonable to share the space. However, mixed personalities and a break-up have caused two of the girls to move out. The first girl moving out only raised my rent by $70. However, when the 'ex-girlfriend' of my roommate moved out, my rent increased another $130. She offered to pay the increase in my rent because we've been family friends for almost 22 years. As of now, I haven't seen what she owes me for July, and August rent is due in a few days. 

Needless to say, working part time as a full time college student makes financial burdens like this even more overwhelming. 

What have your roommates done to you in the past and how have you coped with it?
<bot>: Two girls moved out of my apartment causing my rent to increase almost $200/mo since I started living there. One offered to pay for the increase from her moving out, but I have yet to see any money from her.
