Well look at it this way. Unless her LL is something verbal, the best way you can make deposits while not pursuing too much is through your actions. Only you know what the best actions are...cooking dinner, working around the house/yard, cleaning bathrooms/kitchen, helping with kids.
It concerns me that she is still connected on facebook. If it were me I'd want all that disconnected and access to all her accounts, phone bill, etc.
The reason for that is...she is putting the burden of trust on you without going the extra mile to repair the damage she's done.
