Should I stop playing house ?

My boyfriend says at some point he's going to want to be single. I had said you dont have to promise me forever but can you at least stay during the holidays and he promised that. But I realized honestly I sound like a clown. What kinda promise is that? Why should I be giving him my everything and playing house if I know at some point he's for sure going to want to break up and experience other women. It's good hes being honest. But thst kinda thing makes me not want to cook for him massage him or open up about my deep secrets if I know he's planning on getting out the door faster than I anticipated. I know I'm not always in control of everything but I did tell him I am looking for a long term relationship and we've been together about a year and a half. Im hoping to at least be together two years. But it feels like im kinda begging him to stay with me which is an off vibe. Now im kinda turned off to the relationship and almost feel like if it's like that then maybe we both should just be single now. Why shoulf we drag it out and play house when he knows he's not truly in the relationship. Let me know your opinion. Should I just be single?
