Wasting time with an ex


So my ex comes over about once a week and we chill/watch netflix…I sense he wants more but i’m not interested – I start thinking this isn’t fair to him – but we haven’t had a conversation about this so I could just be making assumptions…
Then i question why i’m hanging out with him when I do want a relationship with someone (just not him)
Can you help me gain perspective on what i’m doing? I invite him over, then don’t feel that great when hes there because I feel pressured to do more…
