You don’t need to be in a relationship to be happy.
Often we search for happiness in others instead of within ourselves, which is just setting yourself up for failure and heartache. When we do not value ourselves, we set the boundary for others to perceive us in the same way. If you let someone treat you terribly, why would it get better for you?
No one is going to fix your issues for you. It’s not probable. Just getting into a relationship to say you’re in one or so that you are not alone is not the purpose. It is possible that you will not be ready for a relationship. You may be disappointed or discouraged in a relationship because you are not looking for someone, you’re looking for yourself.
Ever heard the phrase, “I don’t have anyone to look good for anyway”? Yes, well this is saddening because you can look good for yourself! Why not? Get dressed up and go see a movie you have been dying to see or sit in a coffee shop by yourself. Do something for yourself, not because you want to please others. Not because it will make you look better. This is your life, do it for you. It’s better to be alone than in a relationship where you know you’re not happy.
If someone feels empty, that is not something that anyone can solve for you, that is on you. Going from relationship to relationship is not going to take away the issues you carry underneath — It can mask or increase this but never fully extinguish the conflict. Not being comfortable in your own skin will not make it easier trying to be comfortable with someone else. Don't to be someone to please others. You do not owe anyone anything and they do not owe you anything.
Waiting for someone to love you back or obsessing over someone when they don’t is rather foolish. This is the time to discover who you are, your strengths, your weaknesses, your desires. Love yourself. Or learn to love yourself. Self-love is as simple as respecting and accepting yourself for who you truly are: the good and the bad, past and present. Treat yourself the way you want to be treated. Loving yourself also gives a person the ability to realize when they are not being treated okay.
