Yes, of course! But you cannot make a true real life with that person that will last for many many years. It will be something like a remedy from this world.

out of sight, out of mind, it will not last for long, this is my humble opinion

Yes, of course but falling in love is hard enough when you are in a familiar comfort zone. Think things through and determine if the benefits outweigh possible risks and consequences. Search your heart as to whether you can leave behind family and friends if you will need to another country and whether your partner would be able to do the same. Even so, the most important thing you can do is use your common sense. It can save you a lot of unnecessary heartache along with potential financial woes if your chosen partner is not the one for you.

Yes. If its' ( LOVE) is accepted in right spirit.
