Eh, that's okay. People make that out to be like it is so weird, but I think they blow it out of proportion. I mean, doesn't everybody have those voices that scream at you to kill people and burn things?
...No, I'm kidding of course. ....Mine tell me to burn
people and kill
things. ...I don't think they're the brightest voices out there.
(Seriously, hopefully it goes without saying that I'm just kidding about all that. LOL!)
Anyway, a wise, bizarrely effeminate man often said "Compare and despair." ...Okay, that man was Stuart Smalley, a fictional character from Saturday Night Live..... but he's still right about that.
Believe me, I know this is about a million times easier said than done.... but if he seems to like you just fine, then don't compare yourself to his ex/exes, or to anybody else he may be dating if you two are not yet exclusive. Obviously he likes you or he wouldn't date you. Obviously he finds you attractive or he wouldn't date you. I can't speak for him, but I know for me personally, physical attraction is only one small part of what makes me like a woman. Sure, you have to find your partner attractive, but I am personally much more interested in WHO they are as a person. I often find myself MUCH more attracted to somebody who may not be the super model/cheerleader type.... but who has a great personality and gells with me very well. I would NEVER be interested in somebody who is super attractive, but seems self-centered and shallow.
So, as best you can, don't compare yourself to others. If he didn't like you, he wouldn't be dating you. Again, I know that is so much easier said than done. It just takes a little time and practice, though, and learning to be more comfortable in your own skin. Believe me, I of all people know how impossible that can seem. But if a fugly monster like me can actually learn to be comfortable in his own skin, then certainly a lovely young lady such as yourself can as well.
Your friend makes a good point, by the way. He goes out with all these women you think are SUPER attractive.... AND YOU. So that must mean this guy considers you on par with them in his mind.
I will confess that I may have to defer to others on this one. I don't know if it is just me, but I find his reaction to you asking about the painting weird and I find keeping in touch with an ex weird. I mean.... I guess for the latter there are certain qualifiers. Like how long where they together? How was their break-up? Was it fairly mutual and amicable, or was it messy in any way? You obviously don't know those answers... at least not yet... but I just personally never understood any reason to keep in touch regularly with an ex. Unless you HAVE to (such as if you have children together). Even if you parted in a fairly friendly manner.... I still never understood any reason to keep in touch. To me, it just seems healthier to make that clean break. For the both of you as well as for any future partners you may have.
Maybe that is just me, though. I dunno. If you and he are becoming more serious, though, I guess that just depends on if it bothers you or not. I suppose if they truly remain just friends and don't cross any boundaries it could be okay if it doesn't bother you. If it DOES bother you, it is maybe something to discuss with him, though. At least if/when you two become more serious/exclusive. I guess approach it as diplomatically as you can, so to speak. In the grand scheme of things, he's an adult. If his friendship with his ex is something he is unwilling to give up, that is up to him. But, if it bothers you, that does not mean you just have to be okay with it. May be a reason to part ways if neither can bend.
...Though I do feel I'm getting a bit ahead of myself there. I don't necessarily think you need to worry about it to that degree yet. Especially if you two are not yet exclusive. It sounded like you said he's still presently dating other women.
As always, best of luck to you either way. Believe me, I know these self-doubts can be a killer. I know it isn't easy to quiet them. ...But, believe me, you can get better at quieting them with some practice. When you do, it gets a little easier to tell when you may be worrying yourself for no reason, or when you may be sensing actual problems. Not that it is ever 100% clear, unfortunately, but you at least get a little better at sifting through.
Good luck!
