Of course I trust him, he's very trustworthy. He's never lied to me or me anything. I believe I'm naturally jealous since I'm not exactly too nice to look at,so I guess it's pinpointed at my unconfidence due to mom again ( thank you for calling me names all my life >.> )
At the risk of invoking a clichÈ, I'd say that if he really loves you, and if you're as close as you say, then your looks shouldn't matter much to him. And it seems to me that you have plenty of qualities to make you appealing to him: your kindness, your affectionateness, your openmindedness, your honesty, your artistic talent, your creativity, and so on.
Still, I know WAY too well how it feels to be insecure; it's not an easy thing to overcome.
And honestly, your artwork is amazing. Like I said before, I'm not a Sonic fan, so for me to give you feedback on your art would be like a lion asking a shark what kind of antelope it thinks is the tastiest (I can appreciate the medium, but have no experience with the subject on which to form an opinion), but if and when you make some LBT fanart, I can guarantee you a fan and a consistent reviewer.
Speaking of art, I noticed that in your DA journal you expressed disappointment that no one else on DeviantArt made you any birthday artwork. If it would make you feel any better during this difficult (to make an understatement) time you're going through, would you like me to draw you something like a belated star day and/or sympathy card?
