After a while, I think there is something wrong with self-deprecation. If it's all you tell yourself you will manifest it. So if it wasn't true before it definitely will become true.
Also, what does it say to your partner? If I outwardly was saying "Hey, I really truly deeply hate myself and can't bare to look myself in a mirror, but I'd love to spend time with you?" I feel that's selfish, or at the very least that self-absorption will lead to neglectful behaviour and unnecessary barriers. Sad but true.
