My stepsister problem

Im 18 and my 16 year old stepsister just told me she likes me a lot and has even before our parents married what do I do?

she is your sister even though you arent blood related, move on.
it wouldnt work anyway

I would say thats nt a good idea because yall are related even tho its nt blood blood related bt still... then again who are we to decide... its yall life... yall shud decide what yall think is the best 4 yall...

go for it. you know if you like her aswell, you cant stop loving some one because your told to. people may not agree wiv the relationship but who cares what other people think when you have some one you really love in your arms
