Is he into me?

Me and this guy have been going out,we ve had sex twice already. When we first met, he told me about his ex fiance who cheated on him while he was out in Afghanistan, so he hasn t really dated since. Well I stayed the night one night and he dropped me off at home, told me to get some sleep and gave me a kiss ( we were up most of the night lol) and than all day he didnt text me back, so the following morning i went off on him, he works a job full time, and hes been sick so he explained to me his meds are giving him sick side effects and than ever since hes made sure to text me, he s consitent, makes sure i get a goodnight text. He also wants me on birth control, and says he ll help me quit smoking
