Thanks for the response guys, special thanks to rewire! You are right rewire, I should let the relationship go with the flow. Nobody has seen the future.
There is one more twist in this though, she is pressuring me a lot to have a baby already, which I don't want mainly because, I think things are gonna become more complicated with the 3rd person in the family. This baby thingy is bugging me a lot as well. I just don't know what to do, I have told her to wait for 3 years or something. But she says that's too much, she can't wait that long! Btw we both are 24.

Thanks for the response so far. Really appreciated.
