Geminis literally have multiple personalities...
Your sign is one of the most versatile in the Zodiac. As the sign of the Twins, you have two very distinct aspects inside you. Potential partners may not always understand why you seem happy one moment and then sad the next, but it's just part of your complex nature.
No need to make apologies. In order to integrate these two "people" living inside you, you may need to listen carefully to what both your mind and body are saying and find a happy medium.
If you need more time to yourself, your outgoing side may scream for attention - but you need to figure out if that's from others or if you need "me" time. Seeking balance is key to your happiness in love and in general.
