When ever he does reply he says sorry I didn't reply. I always say its okay. Is it me or him?

Me and this guy have been talking. We have hung out and kissed and stuff but he always is busy and "forgets" to text me back. Well i always text him first and keep the convo going. I really want it to work between us but i feel like he is loosing intrest in me. i mean he sends me kissy faces but I don't know if he means it ha. Also he plays sports, i looked at his schedule for this week and he has 1 day off. so just to see what he would say i asked what his plans were for this week, he said sports. So then i asked if he had any "free" days. he looked at it and never responded. When ever he does reply he says sorry i didn't reply.. i always say its okay. is it me or him?
