I want someone who is serious in life
serious about what?
I think your expression itself doesn't show seriousness and it attracts the opposite of what you're looking for,if you're looking for love then it lacks inspiration.Who can say he's not serious here?What do you have on offer to show that you're looking for someone serious?You have to be serious yourself first then surely you'll attract the people of the same magnitude!Those who are preying on ladies would mostly be attracted by your statement.You just need to be serious on your own then someone will come your way and in that sense you'll be able to assess scammers to genuine people.You need to outline your expectations,dreams and who you really are.Remember we're serious in different things but that's still (in life).I can be serious by being a Workaholic and that's life,I can be serious by only keeping time to come home and that's still life.So you need to be clear to what you're really looking for.
