Being a wallflower does not have perks

I am a foreign man who moved to Peru just recently because of my job. I am an American, to be specific. I l already spent 6 months in Peru and I have tried to mingle with Peruvians and even attempted to date Peru ladies but to no luck; I always end up getting rejected. Since then, I think ever since I migrated here, I have become a wallflower. It is as if these people do not see me at all except for those whom I socially interact with because of business. I have been trying to be part of the society here but I ended up being alone. Being a wallflower is actually no good because I am pretty lonely. Anyone out there who cares to help me out of this situation?
