belle, i'm sorry you are struggling with trust issues after what happened with mark. poop on him for that. i do think it's good that you are not ignoring those feeling though even if they are just your own anxiety. i think i'd talk to louis and just ask about the FB thing because it is harder when you guys are long distance most of the time.

just out of curiosity i'm wondering when you met his sister did she say anything about her brother to really give you an idea of who he is in relationships? like, "he's such a great guy and deserves a good woman", etc. or did she make any digs about him concerning his character? i ask because hey they're family and they'd know what he's really like even if they are biased. also, do you know much about his former relationships and what happened with them?

as for the marriage and family comments i think it is fine to talk about in a general way discussing what you both want out of life, but i'd be concerned if he's saying he wants that specifically with you already. that would be a red flag at such an early stage. i don't see any reason why he would need to discuss that already even if he felt that way. discretion can be a good thing. of course it's quite flattering though!

enjoy the ride girl. you're in the honeymoon phase of the relationship so everything should seem perfect.
