'I was nothing but supportive and caring of him. This entire story was @mattybgratefuls story. I'm sick of the excuses,' she added.
'It's completely unfair. Apparently I don't matter.. What can ya do.'
Lauren also responded to another fans comment claiming that it was unfair of him to speak about their relationship in public.
'It is a real shame for sure after all I did for him to turn around and say that and not be a man and speak to me in private about how he was feeling.
'I'm such an open, non judgmental person and the fact he couldn't discuss this with me hurts. I asked him all the time how he was feeling about everything and he always just said great!' she wrote.
'Honesty, communication and being open are so important in relationships, something he wouldn't understand because he'd never been in a relationship ever. Also something that wasn't fair on me.'
The comments come after Matthew confessed their relationship issues at the dinner party.
'She wants someone who can't get enough of her, hands all over her and be thrown on the bed and do stuff, and I just I can't give her that,' he began.
'The reason I'm not able to show her the affection, the attention that she wants is because I'm just not attracted to her and just I'm not feeling those urges,' he added.
