I find it interesting when you say he was more forthcoming about what he wants in relationship before you were. This is the first red flag. If you want a holiday and to meet him all well and good but I'm sure every one here will say to you do not be loose with your money let him look after you and never get drawn into the visa route. Plus NEVER fall for any stories about him needing money for ANY reason it's all lies but this could start after you meet. You know your mind and nothing any of us say will change it, just remember we're all here for you without any judgement.
