Confussed

Where do I start? I was browsing on a website and received a message from a female trying to hit on me. I politely told her I was not interested on females but we can be friends. We continued talking for a while and out of the blue she starts to tell me about a male friend that is single and looking. Fast forward the male friend and I have been talking for at least a month now and he's telling me that he loves me and wants to marry me. He is a wonderful military man with a strong mind. Knowing that we only have been talking for only a month got me questioning if his feelings are real or not. What should I do, should I follow my heart and do it or should I sit back and let it take it's course?
