Can I get some advise

Recently my ex broke up with me, I been having a hard time to cope about it. Turns out he stopped loving me a while back but didn’t know how to end it so his excuse was that he needed time... and it’s been over 2 months, he’s doing him, having fun, going out with his guy friends, and living great. While my only way to not feel depressed is to drink my pain away to feel good and forget all the stuff I’m going through. When in reality I still end up feeling worse once the alcohol drains out my system.. He was my first bf and honestly I don’t know how to deal with this breakup, don’t know how to forget the 2 years and a half I spent with him... Guys make it look so easy to move on but honestly it’s been so rough on me...🤦🏻‍♀️
