my boyfriends job is really slowing down he went from bringing 300$ home to 145$ I wasnt so worried about maturity leave till today hes moving in and taking on alot not only with being a dad but being a family..I feel guilty that he wants to take on my bills as his own put our money together I feel like its not his responsibility..I love the man to death and he loves me the same but always being on my own paying my own way and then letting someone come and help me takes alot for me to do im very independent I really dont know how to handle this or what to do were going to be a family I see him as my little family but how do I just let him step in to help with everything should I even let him help?
