Exactly what I would recommend *edit*(that you find other friends that won't pressure you)* . Who cares what others think or whether you're in conservative or liberal country. When it comes to personal choice matters societal mores outside of things being immoral or illegal are none of society's business. Besides in every culture there may be a bit of emphasis on families which is good on the whole for society but individually there is always a good number of singles that enjoy just that, even if temporarily. That is, enjoying being single. Take care of you, first or nothing else matters. Work too hard to fit in but sacrifice your own actual goals and desires and that only gets you a life of unhappiness brought on by the feeling of obligation to things you do not want.
You're not brainwashed tho. You wouldn't be here questioning things and asking about others' opinions and accepting what I'd previously said if you were

you can still think for yourself you just need to stand up and assert this.
Good luck
