To give up or keep trying on the relationship

Sorry this will be long but i have nobody i can open up to. So i broke up with my partner of 4 and half yrs on 1st of Jan this year. We have our issues and my mental health is horrible, i broke up without the real intentions of wanting to. I voiced this to him and since then we are still very much actively pursuing each other. We sleep in separate rooms but are still intimate and cuddle on couch, kiss eachother the whole deal. On the outside we look like a couple still. He told me he got tinder, has been talking to girls but isnt keen on meeting. I said that once he meets with a girl it would then be his answer to me that he no longer wants this relationship. He explained to me that he likes how things are currently but is scared to say yes to the relationship because he doesnt know how long this good feeling between us will last, that is fair and my goal is to be able to continue this good side and never have him question it. I should mention i have stopped the pill as it definitely has some bad side effects of mental stability and depression. Since being off it i have felt more clearer on our relationship and have been the best version of myself. Im feeling confused because we have booked a holiday for easter, we are still making plans for future trips and dates.I guess my question is do i keep pushing for us to have a relationship or just leave it because he is using tinder. I know its going to be harder this time starting the relationship and we are going slower with it but i cant help thinking i can do all this and him still decide he will finally choose tinder over me.
