2 sessions in a row MC and exBF "ganged up on me" and were like "don't leave" it makes no sense, if I were you I would stay, etc. it'll cost thousands (???) to relocate. Keep D stable, etc. etc.
First of all, it's not ganging up on you if they are offering you advice, just because you don't like the advice!
Second - YES, it DOES cost thousands to move usually, because you have to come up with first and last months rent, you never get back all of your deposit on the old place, you have to rent a moving van (assuming you have friends who will help you move and don't have to hire movers also), and if the utilities are not currently in your name but in BFs name, you will likely need to pay deposits to the utility companies. So - as an example - ASSuming your current apartment you paid first and last months rent when you moved in - you give one month's notice and don't have to pay rent that last month (saving $1475). But you have to come up with first and last and deposit for a new place that rents for, say, $1100 a month - that's $2800 if the deposit is $600. Add in $150 to rent a truck and buy pizza for friends who help you move, and $300 in deposits for various utilities. Assume you get none of your deposit back on the old apartment (you have had a child there, after all, and landlords usually do find a way to not give you the deposit).
That makes $3250 in new expenses minus $1475 last month rent = $1775 you have to come up with. You would have to live in the new place for at least five months before you recouped that expense. So no, it might not make sense to move to another apartment yet, at least not until you have your a better idea of what you are doing.
Now - if you could move somewhere that doesn't require first and last, OR if you could just get a room mate in your current apartment (yes, I know, you keep insisting that is not a possibility, but financially it's a better deal - think about it)....
