If you truly want to heal yourself and move forward, don't text him. Do like what is recommended to anyone after a breakup: spend time with close friends (in your case, preferably female) and family, and find something about yourself to work on and make better. And while you're at it, enjoy being single again and doing things you couldn't do while in the relationship.
The guy doesn't sound like he knows what he wants. Or he's a player and wants some backup girls on his strings.
Also, think for a moment: things were going so great, then he suddenly cut you loose for other women. What does it say to him if you come back? You might as well say, "I love drama and turmoil. Take me back so you can b**chslap me again, I like it!" Do you really want to go back to a guy that seconded you for MULTIPLE other women?
Your "gut instinct" is what I know plenty of player-guys feed on: the idea that a guy who is so flawed can be changed, or that now he knows what he's missing and will become a model-man for you. He won't. Only he will change himself. If there really is a destiny for you two to be together, then you will eventually get back together, and it won't be because of a direct contact after a breakup like this.

based off past experiences with me and others, don't contact him. He broke up with you to explore other females. Let him. He chose that and don't be available to him when he decides he wants to come back because when he does, there's a 90% chance it's going to be because none of the girls worked out and you're his plan b. Don't be a doormat. Don't think that him leaving and coming back is "fate" it's not. Personal experience with contacting ex, we fell out 2x and both times I reached out to him after about 2 months. We were on good terms after the first time but he didn't want a relationship. I convinced myself that he'd change his mind on day or something but he never did. He treated me like an option and even though I hated it, I still preferred that over him not being in my life... I was stupid lol... the second time we fell out, he disrespected me to others and I shouldn't have wanted him back in my life but I thought about him constantly and took a chance. Reached out and said I wanted to fix things. He had a friend of his call me and the friend left a voicemail saying he doesn't want me, I'm crazy, etc. since that happened, I've honestly been a lot happier. Don't waste too much time on your ex. I spent 7 months stuck on mine and missed a possible blessing (another guy). Allow someone to come into your life and do you right because you're ex won't.
Hope this helped❤️
