Fiancé's anti depressants

My fiancé suffers from depression. It's really been something that's caused a lot of issues for us. Recently I finally convinced him to go see about it, and he's made a lot of progress. I'm not sure what medication he is taking, but he takes one pill a day, and since then he's changed a lot. Not only is he more independent and mentally stable, he helps me with my issues a lot more too because he feels stronger emotionally. But he's also not as romantic, not as loving (although I know he loves me) he functions a lot better on his own and doesn't need my help anymore with a lot of things. He doesn't really tell me he loves me anymore, and although I'm happy he's doing better, it feels I also have some adjusting to do with how he acts. I know it's good for him, but can anyone help me on how I can get use to my fiancés different mood ?
