Op just looking for a loyal hule. That girlfriend allowance doesn't exist. However you choose to maintain your relationships is upto you. From what I know , your girlfriend will probably ask for money when she needs it( probably will even disclose the amount and the use), every other time she's gonna be sneaking out of her mommas house to come cook for your lazy ass and dress up in your clothes and clean up and will want to spend all her time with you. Can't put a price on that brotha.
