My husband doesn't love me anymore

Danielle
We started ttc a year ago. Two months ago my husband told me he didn't want to have a baby.. he works in a school with kids all day, we had been fighting more over stress of not getting pregnant.. so we stopped ttc... Less than a month later he tells me he's not in love with me anymore and that he wants to me alone. He's been in the guest room for almost a month now which kills me, but I haven't given up on trying to make things work with my husband. I love him, we've been together for 12 years, married 7.5 and I can't imagine my life without him.. I'm now stuck between not wanting to give up.. and not get my hopes up.. it's been an emotional roller coaster and I can barely even focus at work. We're still living together until we can save a little money as we just cleared out our savings buying a new car. I don't know how long I can go on like this and some days feel I should just give up now and start moving on... I swore I'd try til he served me divorce papers.. but I don't know how to start the grieving process til I know for sure we're done. Anyone been through something like this and if so.. any suggestions to keep me sane during this awful time?!?
