Spending enough time together

For couples who do not live together and have been together for a few months…how much time together is enough? I have my own place and my boyfriend has a roommate. He comes over on saturday night usually. We usually don’t spend time together during the day though. We go on a date and he spends the night and usually leaves the next morning. We are both in our late 20s and work a similar schedule (usually no weekends). Honestly, it doesn’t feel like enough to me…
