I Need Advice

My head is spinning like insanely. So my boyfriend or not boyfriend has had his feelings for his ex resurface. So he doesn't want me to go away or leave because he doesnt want to lose me but he cant be with me whilst his head is split. And im praying its just him properly moving on and him being scared too so everthing is rehashing... And ive mentioned that i should take a step back but everytime i suggest like going away he freaks out and states that he doesnt want that. But what if these feelings dont go away or worse he decides to act upon them... He says he wont but ya know.. guys right? no offence but uh yall are confusing like. What am i supposed to do or how am i supposed to help him get past this because i love him dearly and i know he loves me... i can just see it. Everyone can. Even his best friend is annoyed hes doing this to me. And my best friend just says considering how he looks at me hes not gonna just let me go. He wants to give it a bit to see if these feelings go away... should i give him this time? i understand this is tearing him apart but doing this is tearing me apart... so do we both just be teared apart until it goes away or do i just let go? i know i dont want too but... if it makes it easier for him then shouldnt i?
