Reality check.....am I worrying over nothing or its coming to an end?

I think you are being paranoid and suspicious of your boyfriend. You have only been dating for 4 months and he is making every attempt to spend the weekend with you. Me and my boyfriend have been dating for one year. We spend Saturday to Monday together because he is off on Mondays and works Tuesday through Friday. I used to feel insecure at the beginning and now I trust him. There is nothing at all to indicate that your boyfriend wants to end this. So try not to worry so much.
