Sometimes the first few days after a reconciliation can be quite weird or awkward.
I've experienced it first hand, and suggest you just attempt to relax, allow both of you the space to feel each other out and ease back into being together

He may still be apprehensive about your jealousy and you're insecurity is probably more evident than you realize, but you both want to be together which counts in your favor, nobody said it would be easy.

Well nobody except the media when they depict long (or not so long) lost lovers.

Romance is nothing like the fairytales, soaps and movies would have us believe.
We're human with our own sets of flaws and fears, love doesn't make those magically disappear.

Give it some time, but by all means talk it out if you feel its not dissipating and the connection between you is not improving.
