How do I know

It’s been a year and 2 months since a 2 year relationship ended and everytime I think I’m over her I see her in my dreams. I smoked a shit ton of weed everyday for the past few years and quit about 2 months ago and since then I’ve been having such vivid, realistic dreams. I relive those wonderful moments of our relationship in my sleep and when I wake up I’m crushed. Even when I haven’t thought of her in days it always comes back. I try not to dwell on it but I still miss her and love her. I spent years trying to get with her and all that for me taking it for granted. I’ve been trying to date but nothing feels right, I just don’t know how to move on ya feel
