please help....needing support

Hi guys... so after 1 month of no contact ( I blocked my narc on everything...phone, text, social media ect)...he came into my work yesterday. I bartend... so him and 3 of his friends came in and the thing is that I became friends with some of his friends while we were together...so I felt bad kicking them all out..and to be honest, seeing him jolted me and gave me that surge of energy that I needed or wanted I guess....I ended up going home with him and having sex with him..I hadn't had sex in a year with him ( since we broke up)...I immediately felt sick to my stomach after... but I had rode my bike to his house so I had to wait until sunrise to leave. The minute I saw the sunrise I snuck out of his house and I walked home. He just texted me asking if I wanted him to drop my bike off somewhere..Like it can't just be in his garage for one day...I don't know why this hurt me ( probably cause my stuff use to be at his house all the time ) and now it feels like he can't even wait a day to for me to be able to grab it....why does it hurt so much....ugh I feel so gross...and like I took 1 million steps back....I work at 2 bars in our local area and now he seemingly goes to those bars all the time.....and he asked me last night why I hadn't returned his texts and I told him I had blocked him...ugh why oh why did I do this.... I had a 1 on 1 with Goldie a few weeks ago and I felt strong...I can't kick him out of the bars I work at and whenever I see him it is so hard...also should I just tell him to lock my bike to a tree or something? and I will get it when I can...? It may get stolen but I really don't want him dropping it off...please help
