go out and get
your life into some sort of normality .. always being there for when THEY want you is totally wrong .. if they are serious about you in some form of relationship at any stage then they have to show it .. its a 50/50 thing .. not in from what you are saying a 90/10 thing ..
life does and will go on ...new people will appear .. friends will be there for you .. only if they are true friends ...
as for the financial problem .. well only you 2 can sort that out ... go and seek legal advice first tho .. thats the major thing YOU have to do ..
hope summit works out for you in the long term tho .. but dont sit around feeling sorry for yaself go get a shag

sorry
