Can I still miss him even if I’ve fallen out of love?

I found out my partner had emotionally cheated on me, and that cut so deep. But I was willing to give him one more chance. It’s been over a month, and my feelings are nowhere near what they used to be. I find myself with these walls in place. I still care about him and want the best for him and can see myself forgiving him… but again, I don’t feel the way I used to. I question if I fell out of love, even though a part of myself is still with him and doesn’t want to let go. I just don’t know what to do. We’ve been together so long and my sister was helping me plan a wedding… for everything to change so much, I’m caught off guard. I hate imagining him with someone else, but a part of me just wants to be on my own again. I don’t really want to feel like I’m pulling someone along when I feel like I need to heal myself
