Possibly leaving alcoholic husband

I packed mine and my sons bags this morning. We’re staying at my moms house for awhjle before going on a vacation, a vacation that was suppose to be a family vacation. It saddens me but I can’t take it anymore. He’s hurt me so many times. He’s let both of us down. He didn’t come home from work. He didn’t tell me where he was. I said we needed space. He took advantage of me and went out drinking two more nights. He stayed with his brothers band out of town. His family enables him and acts like I’m the monster that I wish to have a sober husband. We’ve been going through

IVF

( stupid on my part I know). FET failed. My husband never asked me. Never asked how I was. Didn’t help me with anything. He called me lazy for falling asleep most days cuz the meds make you exhausted. He said I do nothing when I’m a SAHM and literally do everything except work. All he does is work and party with friends. I’m sick of never being a priority. He lost his wedding ring days ago so while he was out he had no ring. I decided to take mine off. I feel free. I’m not sure what my next move is. All I know is I’m trying to stay strong for my son. No more wondering where he is or what condition he’ll be like if/when he even comes home. Time for some me time.
