what is the next step?

[moving-on]

hi i have 2 children with my ex. we were not married. i have been on my own with the girls since aug 2010. i feel i can no longer keep waiting for him to see his girls. he wont agree to a set day and wants to come over when it suits to put them to bed. i have let him do this as i want them to see their daddy but i no want to start moving on with my life and want set times from him so i can organise myself, my problem is he has moved back into his mums and sleeps on the sofa. his older brother (k) also lives at home and tried to kill himself last week. he is a recovering alcholic who has now turned to drugs. i have said i dont want girls round there (nannas house) until k is stable (ie. got help) but obviously therefore keeping girls from their dad. i dont know what to do? i want to sort out visitation, i dont want then at nannas untill k is better. can you advise me?

Do you think that K will harm them in anyway or is a danger to them? If not then as long as their dad and grandma are with them then what harm will it do to go there?.
Is there a reason why he has had to move back to his mums? Is it financial? Obviously it would be better if he could afford a litle flat or something where they can go and spend some time with him.
Obviously it would be easier for you if he could have them at set times, say every friday night and saturday, or every other weekend or whatever, once the living situation has been sorted.
