What do you think?

Heres my problem my recently ex & mother of my little girl has a step father she just met him last yr. she was adopted. Hes a long haul trucker he sends her very suggestive & even ographic mess. on her phone. she eagerly awaits his trips to town & hang out in his truck when he comes to town, she says watching movies she has a whole house to do that in . We still share the same home but he doesent come over like he used to when he was in town & we were together. sounds fishy what do you think?
