Is this okay?

So I have endometriosis and PCOS. There is nothing wrong with my husband. He could easily conceive with someone else if he wanted to. For the last three years a

I've had 2 surgeries and 5 failed IUIS. Two weeks ago he said he doesn't love me anymore, hasn't loved me for the last two years and left. I asked him to try to work on us, because that hit me like a brick wall. Anyways he decided to work on is, and instead of sleeping at his friends hes sleeping on the couch. The thing is I hate cooking, but he now has me cooking every night for him, and packing his lunch everyday. Apparently this was one of the problems with our marriage. He has sex with me frequently, but he wont say I love you. He bought me flowers Saturday when he went out to do some errands so I thought he was having feelings again, but I'm just so confused. I'm trying to do everything to the point where I've taken over his household chores as well, taking out the garbage, taking care of recycling etc. I dont know I know I want things to move faster, but damn I'm exhausted. I'm a registered nurse too so on top of all this I'm pushing through this pandemic.
