Hey all, so I have been dealing with self-esteem issues since high school or so and am currently in a LTR with my wonderful boyfriend. Now and then, I get overwhelmed with negative thoughts about myself and fear that this will end up pushing him away. He's not aware of the extent of my low self-esteem and I feel like he would find me undesirable if he did.

He's not a very complimentary person (but is affectionate in other ways) so I often find myself aching to just hear that he finds me attractive to just quell my doubts/worries. He will say I'm pretty or beautiful on very rare occasions, and if I dress up for anything he will compliment my outfit rather than how I look in it. 

However, he has on more than one occasion mentioned the attractiveness of other girls (celebs, ex-gf's, friends, etc.) which has always left me feeling a bit down. I don't really care about him talking about a celeb's looks but he did mention that his ex-gf had an "inexplicable beauty". He is quick to say that I have a great personality and that we have a really healthy/functioning relationship but it's nice for a girl to hear that your dude is attracted to your physical looks.

Once I'm in a negative thought spiral, I start thinking that he's only with me because it's regular sex and it's a comfortable companionship, that he's not actually attracted to me and any sort of tactile stimulation would obviously arouse him, etc. etc. We have sex often and he's said I'm the best he's ever had but he has never once complimented any part of my naked body or made me feel "wanted".

I have had a couple therapy appointments with campus counselors for my self-esteem and confidence issues but nothing has truly helped yet.

If anyone has any insight on how I should handle this, if you've gone through this yourself, please leave me some comments.
<bot>: Suffer from low self-esteem, sometimes it gets really bad and I doubt if my boyfriend is actually attracted to me. Realize this is unhealthy and want to change. Advice please!
