Should I worry?

First off, if you have never met each other, how do you know that this is true?

In the end, you have to make your own decisions and figure out what's right for you. The only time you need to worry about another person's opinion is if it will affect your life. If his mother's opinion means that her son is not allowed to see/talk to you, then why don't you suggest that you go to his house to meet her?

I wouldn't worry. It is common for moms to worry. Besides, you're not going to be 15 forever.

15 and 16 sound are really close ages ... you could have that type of age gap even having been born the same year. It's really not something to worry about. It's true that he might take into account his mother's opinion, but you'd be better off asking him what his thoughts are about this situation. Work this out together and your relationship can grow from overcoming this.

This happened with me! A while back I was talking to this guy who was 18 and I was 16 he was only a year above at college but I'm one of the young ones in my year so I turned 17 before he was 19. His mum wasn't very happy about it at first but once I started to get to know her it turned out find and we got on really well. I think if you both like each other then you should do what makes you both happy. It isn't a very big age gap. If you haven't met her yet just trying being extra mature around her. See how he feels about the age difference and if he is fine with it then if anything more comes of your relationship his mum should be happy because he likes you enough to take things further, meaning you make him happy and that's what counts.

15 and 16 is nothing to worry about. But unfortunately at that age you are not yet considered independent from your parents. But as long as his mother doesn't forbid it then I'm sure she can be swayed. I think if she met you and saw that her son was happy with you she would be happy. Once you're 18 though as much as your parents might not like who you date, it won't be your problem anymore because you are officially an adult who can make their own decisions. I say continue with him despite his mother's opinion (unless she forbids it). Do what makes you happy until someone stops you.

Wait. You have been talking for 2 weeks, and you're worried about his mom? If he is the one telling you he might be trying to get away. You have never even talked to her. You don't even know this guy. Slow down, and stop worrying.
