Unless Marvin absolutely hates MC and doesn't want him dating his mom (understandable) or Luke expresses his own displeasure with Nicole dating a young frat boy (also understandable) and she is swayed by either, I think this relationship is full steam ahead for the moment.
There's also the issue of Nicole stripping. DPC is mainly using that as drama with Lily, but Nicole and Luke split up over this and Nicole cannot seem to find another job that will pay as well. MC is a big drama queen, and while's he's fine dating strippers, he could always change his tune when things get serious.
