Stop feeling like you have to explain yourself to everyone else or justify your decisions. Are you doing what's best for you? Does it make you feel good/happy/fulfilled? Does it feel like the right timing to you?
Awesome. That's all that matters. You're under no obligation to live according to anyone else's feelings, concerns, or opinions about what's best.
When people stop understanding you, stop explaining yourself. Sometimes, silence is the only thing you can offer to them. Stop explaining yourself at every point of matter if they are believing you they don't need it, If they are not then you don't need it to explain..
The people who already made their opinion about you and don't want to change it will never believe you're saying no matter how genuine your actions are. And it doesn't even matter until you are true to yourself.
Life is so much simpler when you stop explaining yourself to people and just do what works for you the best and when you don't care for others point of discussion too because it's our life and we know how to live it in a better way rather then you.
So its our life and enjoy the way you are living it and don't care for others because this is the world in which there will be so many people who will not want you to be settle down.
