Can’t smoke

Ka

Hello, so I was a daily smoker. Couldn’t do activities or any thing without smoking first. I thought to myself I ain’t giving this shit up. Well I met this guy I fell in love with him and for some reason I cannot smoke anymore. I have 0 desire to. I was always chill af when i smoked and I’d always smoke w my brother. Now anytime I smoke I get nervous sick. And it’s only whenever I think about my bf. I’m never nervous around him sober but I just think “what the fuck am I doing?” Meaning I have a bf which is very shocking to me bec I didn’t think relationships are for me. He doesn’t smoke so I never smoke near him. I just get sick even thinking about smoking now but I wish I didn’t :(
