Need advice

Ive been talking to this guy for a couple months almost a year on and off he’s always wanted more than a friendship but I’ve always been on fence about it recently he and I hooked up it was amazing the first 3 minuets the he came instantly I was so confused like how or why is he cumin so fast. So his baby mother went through his phone later that day and seen our messages he called me and told me that she might call and try to straighten me but she hasn’t and I haven’t heard from him at all or seen him around our neighborhood what should I think 🤔 ?
