H e l p !!

My husband is depressed, he goes through it every year..plus he might be experiencing some postpartum depression as well as we just had our daughter three months ago. He’s very withdrawn and basically wanted a divorce but I talked him into a separation. We got married in July, but our together anniversary is on Friday and he asked me to marry him a year ago on that day (super sweetly btw). But he’s told me he’s depressed very badly and I kinda made it worse bc instead of noticing right away I got angry bc I’m obviously full of postpartum hormones and anxiety and he was going out staying out til 4-5 am sometimes while I was stuck in the house alone for 3 months without a vehicle. My mom says to keep saying I love you and be there and keep telling him that kinda thing but I’m torn bc he asked for a separation..(he’s staying in his sons room) and I don’t wanna overwhelm him or suffocate him. I just need advice bad. My mom also suggestion I get our vows printed on a canvas, bc my husband wanted canvases with our vows (he told me when we first got married) and just pretend I ordered them a while ago. That I should make a big gesture and keep trying for him. Which I want to desperately, but even when I tell him I love him via messages he just leaves me on read or when I ask to spend time with him he just says we’ll see. I just really don’t wanna bombard him with my love toward him and make him more frustrated and for him to leave us. But as the days go by I just get more frustrated and sad bc he spends all his free time with anyone but us, which I’m totally okay with…it’s just I want some time too, especially with our kids as a family. Idk I’m just so scared of loosing him and he doesn’t seem like he’s ready to try for at least me. Idk ladies please help!
