I was dating a guy for 6 weeks and everything was PERFECT until the ex reared her head back into his life.HELP?

lets just hope for the worst on the safe side,..... coz if this guy ws serious vt u.. he wud never evn had a slight confusion in his mind about what he wanted!! so he thinks that whatever is goin on btn u... is not as sincere or deep yet.... nd its coz of tat , tat he wants to consider his "options"!! so u don keep ur hopes high up der...... if he comes back.... wel nd fine... if he doesnt.....mayb he is not d one....
