try to engage yourself in other activities, don't overthink about relationship
but if you are hurting then when you want to come out from this
i want to come out because I am the only one putting efforts, and he's just using my body and money and above all disrespecting me everytime
you should come out from this aa early as possible, and told him that you are not happy ... he doesn't deserve you ... I know it will definitely hurt you because your love for him is pure ... but trust me you should not waste your time here ...
don't think about him , he is not good for your mental health ... keep yourself busy everytime , everytime when you feel that you are missing him start questioning yourself that why he is not good for you ... it will take time but you can do it
