It was probably kind of sad that Jack didn't understand why anyone could love him. But then he had spent so long being the screw up, the runaway, and spent so long being wrong that anyone getting past that now got to deal with all of that self doubt. The self doubt that so few people got to see. To most he was the flirt, the charmer, loyal but reckless. The rest he kept hidden because frankly it was easier to keep it hidden. But here Becker was calling him brave and loyal and he wasn't quite sure how to react to that.
"I guess its not how I view myself, and that's not fishing for compliments, its not. It's just hard to see what you see in me, what Rose and Martha keep telling me cause for so long I wasn't. For so long I really was a mess, and I kept pretty bad company in those days. I legitimately have an ex in murder rehab."
How it could feel right being in a relationship with him he didn't quite know. Oh he knew some of Becker's past, and the mistakes the soldier thought he'd made, the various things he'd done that still had him tossing and turning at night. He'd pried only enough to try and help him through it, figuring stories like that matched some of his own and were for the telling when the other was ready. But for now it was all getting very feels'y and Jack was more than a little out of his depth.
"Go on admit it, it's mostly the sex right?" he joked, back to the cocky grin and devil may care attitude that so defined him. "It's not shallow its a vital part of any well functioning relationship and with you, well it's pretty damn amazing." He knew on some level Becker wondered if he could compare to the list of lovers, male, female and...miscellaneous, that Jack had had in the past. It had become Jack's priority to show him that he did. That there was no need to worry.
"You're amazing, and I'm lucky as hell to have found you." he told his lover, returning the kiss as if to secure the point.
