Is this real love? Is he my “soulmate”???

Me and my ex have been on and off for about 6 years now and when we first got together there were butterflies and I was on cloud 9 just sooo happy. And then some things went downhill and that’s when the cycle of on and off happened (I call it a cycle) and now we’ve been single for a year now and multiple times while we were single i thought about him and what it would be like if we got back together.

He’s never cheated or anything, but our communication wasn’t the strongest, he’s lied to me about stuff he shouldn’t have and in situations with his female friends he didn’t have my back. Also, we would get into little arguments and the arguments would blow up and I would just say I’m done and leave which is toxic on my part.

Well, now we’re trying it again and I do love him but now I don’t feel the butterflies or anything but I also don’t feel anger or regret or nothing like that. Can someone help me out. Is this a sign?

Btw the female friend he had isn’t in his life anymore and he hasn’t lied to me and our communication from what I’ve seen in these past few months has gotten a little better.
