HI Lo , Is this man a Husband , a X Husband , a X Boyfriend ? I don't see a problem with taking things slow perhaps preventing the same mistakes or new mistakes you two have made in the past . Being " so serious " I am not sure what that means . Does he mean he doesn't want a committed relationship with you now or ever , wants to also see other women , doesn't want to get married ever , doesn't want to get married for a while , doesn't want to live together for a while or ever ? Does he see a future with you or is he just killing time . Perhaps the two of you are not looking for the same things in this relationship . Perhaps you don't want the same things in life . If he loves and cares for you I don't understand how it can't be serious , one can't turn the emotions of true love and the depth of their love off with a switch . One can be careful and one can and should take things slow . How long were you together , how long were you apart . Who broke off the relationship , was an honest reason given for the break up ? Was another man or woman involved in the break up ? Maybe you can explain a little more in what content he made this statement , a little more information to help us get a sense of the relationship then and now . Give us a sense of who you two are .
