My (ex) fiance  not quite sure if we r still engaged. THis was to be a 2nd marriage for both of us  He has a son (13) from a previous marriageHis son has many emotional issues and is very coddled  TO make a long story short My xfiance recently called off our July wedding due to his extreme guilt he has over his son  he feels horrible that his on feels this way  on occasion his on threatens suicide *(not a laughing matter) but sometimes I and others believe its for attn
He told his dad this w.e that he has in his mind that they will get back together and my XF exsplains that isnt so HIs son has started lying and doing poorly in school he IS brigh  but is never pushed to his fullest potential as no family member wants to upset him 
I know my XF loves me and is goingthrough a rpugh patch it seems BUT I dont know what to do he is not good with confrontation  and is a ppl pleaser 
WE are in therapy *(same therapist) havent gone together though SHE was his therapist  and was the onw who helped him leave his unhappy marriage 
I love him  but I also deserve someone who doesnt run  ANY SUGGESTIONS  has anybody been through this  or at least a called off wedding 
I NEED ADVICE
