Met a lovely man on tinder 6 weeks ago.
He split with his ex a year ago but continued to be friends. And, it seems, fwb. This only came up because we were discussing getting tested for stds and when the last time we had unprotected sex was. Sorry, tmi.
He seems really into us and has met my friends and family already. Everyone says how nice he is and commented that he is a smitten kitten. 
But, I’m wary because of his last relationship. It was only a week before we met that he last slept with her.
He says that they were in love at first but it fizzled out very quickly because they had nothing in common.
As soon as he realised he had feelings for me he told her that it was over for good. She persisted for a bit but then he blocked her.
The thing is it’s only been 6 weeks since we met. How do I know I’m not a rebound?
