What should i do? marriage about to be over?

me and my hubby have been married almost 3 years but been together almost 5 years. we have a 10 month old baby girl. a couple weeks ago he left us and went to his brothers. we have had problems for the past almost 2 months, he wants space now. hes confused about life and doesnt have the same feelings for me anymore, no spark. theres literally nothing i can say to work it out. he simply says he needs time. its heartbreaking when he comes and sees our daughter and he leaves because its the pain all over again that hes not here. i am a stay at home mom so i just raise our daughter and have lots of time to think about us. he says he might want to date other people before resolving our marriage good or bad. he has all the control and power over this issue. i dont want to give up on us..i will do anything. i dont know what to do anymore. has anyone had to deal with this issue before? should i never bring it up again (we only text eachother..every once in a while) and usually i bring up the issue. sorry so long..im just hurt confused and lost because this is a shock and i love my husband soo much! thanks
