I feel like my boyfriend takes me for granted...

How do I play more hard to get? Even my dad told me I'm making things too easy for my boyfriend (not sexually. Just in general). Weve only been together for three months so still fairly new relationship. Tonight we were facetiming and all the sudden it lost connection and hung up. I waited 15 min and no call back or text so I texted him and said cool.. he texted right back and said his phone died.. gave him the benefit of the doubt.

The last time he called me he asked if I was going to sleep bc he was ready to sleep. Then all the sudden he goes "goodnight" and hangs up. So I call him back and I tell him how disrespectful that was and if he did it again I was gonna block him (he hangs up on me often). And he goes "and then you'll come right back".. idk what to do😕 (I know this sounds so childish but I'm actually 19 and he's 21)
