In some scenarios should you get back with an ex?

My ex boyfriend and I were together a year and 2 months. We had a lot of love for each other very passionate love and unfortunately I acted more like a wife to him which he's now not appreciated at all. Examples are I picked out his deck furniture even bought some of it, made a garden at his house, organized his house, we had fish tanks together that he doesn't even know how to take care of, I would clean and do his laundry etc. But we fought a bit here and there because I had an alcohol problem. Also he's never had a girlfriend before and believes couples should only fight 2 times a year lmao. A month ago he told me were taking a break and made me take my stuff from his house. He hasn't talked to me since and won't reply, I have concluded on my own this is obviously a breakup. Although weirdly he still has our photo as his profile picture on facebook and hasn't changed his relationship status with me. But he's been hanging out with this female friend who extremely disrespected the both of us and our relationship before that I had set a boundary with likely to piss me off or just because he's in "I can do what I want mode". She has stds and he's a hypochondriac so likely nothing would happen between them he has said but I don't know... anywho since that awful day (that I didn't know would be the last time I saw him) I haven't drank since. I have now been sober for 3 months and getting my act together. I love him so much and him leaving me so coldly like this had destroyed my heart. I want to just run back into his arms. I don't think he will reach out to me again but I'm wondering if he does what does everyone think I should do? Should I consider taking him back or no because someone who truly loves you never leaves you... I'm wishful thinking but don't want to make any stupid decisions if the time comes
