AL maybe you have strange sources of information - Georgia has on its own free will joined Russian Empire. The main reason for that was threat of Iran Invasion and - very important thing those days - Georgians are orthodoxes as Russians so it was logical that smaller orthodoxal people joins the larger beyond the face of mutual foe. Leading role in this process was played by Georgian colony in Moscow. Later Georgian tzar Vakhtang VI have found shelter in Russia during Turkish attacks. In 1795 Iran's shah Aga Magomet-khan invaded Georgia and ruined Tbilisi - it was reason for Russia to join the war against Persia as we had Georgievsky traktat with Kartli (the way Georgia was named that days). Pavel I signed Georgia's entrance in Russia by will of dying Georgy XII.
Joining Russian Empire saved Georgian nation from genocide and assimilation by neighbour islamic states.
As for Soviet Union - there was a lot of support to Union and communism in Georgia itself. RKKA could not have defeated Georgian mensheviks without it. The fact is not only Russians were communists - its not like Russians conquered Georgia - there was great amount of communists among Georgians too and they prooved to be more power-willing than others. Besides, being caught behind two evils - communists and Turks (that began invasive actions at the same time) Georgians chose the lesser. It was not affair of hostility between of our nations but unhappy concurrence of circumstances which lead to rising of communist regime in our countries. During the Soviet period Georgians and some other Caucasian peoples (like Chechens) were the richest among other nations of CCCP. Oh what we are talking about - wasn't Stalin Georgian

? Or wasn't Beria Georgian? Or wasn't Orjonikidze Georgian? And all of them were the Soviet (and Russian) communist leaders at the same time.
Things are much more complicated than just Russians-bad /Georgians- innocent and good.
Ask any Georgian Veteran of WWII (or Great Patriotic War as we and Georgians call it). He won't say you that he fought only because bolsheviks told him to and it was bloody nkvd's agent behind his back when he looked at the Hitler's tanks from his tranche (as Saacashvili would like him to tell ).
