Also, what's not adding up here: he backed off after you had a bit of an emotional meltdown and after asking if he wanted to marry again. He acted rather coldly towards you and told you to enjoy this time of year.... that is pretty distant and shows some amount of finality. It was a subtle goodbye message, in my opinion. Now he's saying he loves you and that you're his soulmate? Did you initiate this conversation you had where you "talked it out"? Did you tell him that you love him and he replied with I love you too? And you said you haven't had sex yet?

I think he senses your clinginess and is taking advantage of it, telling you what you want to hear. This just rings of trouble with glaring red flags.

I think it would be healthy for you to take a big step back and get to know this person for real and far more slowly. Hold off on sex for a full month and many more dates to see if you truly are compatible first. If he truly likes you, he will wait.
