Don't use my age against me. I don't want to hear it.

I'm 18 and will be getting married in 3 months (was meant to be a long engagement but I fell pregnant. My family doesn't know this yet though) but my family, apart from my mum, has done nothing but make me feel like a child. I'm sick and tired of hearing "You're only 18", "I wish you would have figured yourself out first", "I got married young but it only lasted a few years", "Remember when everything falls apart, you have got no one to blame but yourself", etc. So just because I'm 18 my marriage is already doomed? I have no life experience what so ever? My partner is so well mannered and considerate, so he's given my family no reason to think this way. I'm not a child, I'm a young adult and do not need or want a lecture. They don't know half of what experiences and challenges I have faced over the years because I know I'll be judged. They seem to have this idea I've only had 2 boyfriends so I dont know much but thats not the case. I lost my virginity a week before my 14th birthday and learnt a very hard lesson. I grew up quickly, I matured quickly and luckily found the one who I'm meant to be with early in life.

I'm just over it. Not looking forward to the day I have to tell them I'm pregnant.
