How do I get over an ex that I dated 2 yrs ago?

Ok. So, I met my ex bf (26yr) (2021) when I was 21 and he was my supervisor we immediately clicked and we moved in with each other and everything was going well till his mom. She’s a Hispanic mother who can’t let go of her son- if ykyk. So it didn’t work out. But we were side by side till 2024 and I have bad social anxiety so it’s hard for me to go out and meet ppl. I also don’t want to sleep with anyone at work bc you shouldn’t shit where you eat.
Does anyone have advice to help get over an ex and be more outgoing? I feel like I need to get tipsy before I go anywhere to help with my social anxiety.
