I’ve been dating a guy since mid February and we are both exclusive but he has been dragging his heels in labelling it as a ‘relationship.’ Up until recently this hasn’t been a problem for me as he said he didn’t want to rush things but I saw him this evening and something he said has bothered me.
He said that he doesn’t consider himself single and he’s not looking for anyone else but as we’re not officially in a relationship he said I can still date other men as long as I tell him first. I said I didn’t want to do that and that I only want to date him. He pressed the point harder and said: “until I ask you to be my girlfriend you are free to do what you want.” I asked him if it would bother him if I started seeing other people and he said he wouldn’t have a leg to stand on as I’m technically single. 
He said he will make things official with me ‘when he’s ready.’
We are both mid thirties and both have said we are looking to settle down. We laid our cards on the table early on but now he comes out with this? He has always made a bit of a song and dance about being in a relationship, making statements like: “I’m incredibly picky so will only get into a relationship if I am 100% sure about that person” and “it doesn’t take much for me to go off a woman, I’ve dumped women that I’ve liked over the smallest things.” I’m not sure how relevant this is but he did also say that he won’t be putting any pictures of us on social media as he likes to keep things private; my gut is telling me that he doesn’t want other women to know he’s seeing me. Conversely, he treats me like
I’m his girlfriend: we see each other a lot, I’ve met all his friends and family, he encouraged me to leave my personal belongings at his house for when I come to stay, he calls me everyday and he talks about future plans.
He’s been single four years and claims to be ready to settle down but this evening has made me reconsider whether I should pursue this or get out now?
