A little Space and time

So ladies what does it exactly mean when your SO tells you he needs a little space and time,but still loves you and doesnt wanna lose you?

He says its not a break up..he says if he was going to breakup with me he would have done it long time..he just needs a little space from me. He says we see eachother everyday and he just wants to miss me and love me even more than he does.

Last year he cheated with a co worker..which changed our relationship alot. So im guessing that could be the reason?? ...

He says he still wants us too ttc and get married soon..but he needs some time and space for himself.

I mean i kinda agreed because our relationship did change but im still sad..and i think it would help us too be away from eachother for awhile.

Weve been together for 9yrs

Would any of you ladies mind if your so said that too you?..how would you feel or react?

Edit

I forget too mention he says he needs too get himself together,find a better job and saveup and says i should just finish school too get a career and than everything wont be so stressful in our relationship. I dont know what too believe or do..im confused..i love him so much. I told him not too waste my time if he knows im not what he wants or if theres someone on the side. He said he doesnt have no one else and how he wouldnt waste my time..said if he wanted too leave me he wouldve done it long ago..its just that our relationship needs fixing and i always look stressed out..so some space would fix it he says.
