I must warn you ... you only seeing the children for a couple hours a week will not fair well for you in court if it goes that direction. I know it's hard to consider that at this point, but you must. If it takes six months or a year for her to file, that will be a long time for you to only have seen them for only a couple hours a week. There is a clear motive there. You need to change that quickly. In my opinion of course.
