Is he just not that interested in me? or am I overthinking?

This may be due to past people.. but the guy I am currently seeing, i question if he is actually that into me like he says.. He comes over and we chill, and cuddle, and he spends the night.. But we haven’t slept together in over a week now.. and I don't know if it’s me and he’s just not as interested in me as he claims or he’s getting it else where… or I’m just overthinking and it’s normal… cuz the last guy I Dealt with basically would sleep with me every times we saw each other.. of course he was just using me.. so I’m just not sure what to think… he told me not to play with his heart and that he overthinks things with me cuz I was nonchalant with him in the beginning.. I mean it’s nice that I don’t feel like I have to sleep with him Everytime I seee him, but since that’s what I was used to prior I overthink…
