Relationship Issue

Please give me your feedback

Last March I started seeing a guy. We knew each other previously and just had a nice time hanging out. We started messing around sexually. We spent a lot of time together and on the phone at this point. I would go visit anytime I wanted day or night just to make sure. No one else was around. The beginning of the year things started to slow down a bit, by February I was going by invitation only. I started to get that feeling. The phone calls were not that frequent any longer and we didn't see each other at all. He texted me the other day and I just responded with a shout of the dark that his "friend" would not appreciate home still talking to me. It opened a can of worms. I then learned learned that he had moved a female into his house for convenience, like sharing the bills, but guess what happened. He told me the whole story and said he was confused by the whole situation himself. He has since asked me to see him through this situation and let him get straight. I am now back to getting a call or text every day again. What should I do? In a way I am ready to walk but then again I may want to be with him. Thanks for the feedback and I can take the hard truth.
