Separated single mother...

I’m really going through it right now... I could really use some advice from someone who’s been through the same or similar situation.. (background) I’ve been separated from my husband since august. I filed divorce and custody paperwork (our son is 1 year old) but with this whole pandemic they moved my court date to June. My husband and me were together for 5 years married for 3 months. I left him because we were fighting so much and things even got physical. I love him still but I know we can’t be together it’s not healthy for me, him or our son. Sometimes I feel like the days have gotten better like I can be a single mom and be okay with it and be happy but other days I feel like I’m falling apart... today is one of those days where I feel like I can’t stop crying or be around people who are happy or even going on social media. Please tell me it gets easier.. that one day it won’t hurt to think about not being with my ex husband.. that I won’t miss him so much.. because I don’t know how much longer i can take before I break.
