Thanks. Yeah, I try my best to always think things through but I'm not perfect...hence the user name ahahha. Gah, I don't even think in mindset of marriage. I don't feel it's quite for me
You're right- you're only sixteen. Just go with the flow. Have fun. Don't do anything too stupid.
I get that your boyfriend's mum is probably not too trusting of you, but if you have other relationships, you'll discover that a lot of significant others' parents are a bit like that anyway. Most of my friends these days are married, and very few of them get along amazingly with their in-laws. Don't worry about it too much.
And nobody's perfect. :)
