Awwww well if it bothers you- then it is a problem, no matter how big or small you think it is - especially if you feel it's killing you inside.
It always is nice to let out feelings and share them as you feel better.
For your problem, well i guess this is always a common Problem for girls. They see all their mates etc getting married, dating etc and want the same.
Trust time, and in this case your Parents. Have faith in them to find you someone if thats what you want. But not having someone right no, is not the end of the world. In life there wil be plenty of Oppurtunity to meet someone right for you.
The first person that comes along, isn't necessarily the best person.
I am sure, if you wait, you will meet a special person. Just because everyone else has one, is not the bet way to solve such things and yes i can understand that you may seem two faced but it is not really as everyone has these sentiments. If you are genuinely happy thn it is not being two faced, as your problem only is you wis to have someone lse to you also, but i am sure you are still young and have a great long life.
So wait for someone right for you, not just the 1st guy you see, 😳
Just be patient, you never know what is around the corner, just don't getdown about it, as all girls will have this problem i am sure, 😳 and maybe tell some close friends, you never know their BF's mates etc you might get to know and like and so on.
However, being single isn't the end of the world, even if your mates are all dating. Being single has its Advantages😉
