Tommy may be a traveller ethnically, but he doesn't practice the culture. He married a non-traveller - a gorger - got her pregnant out of wedlock and lives with her. The first is uncommon in the like and the latter two are completely shunned upon for both men and women. I don't think he'd be more involved if they were having a son. It's very clear he's not interested in her and is probably only still with her to not receive backlash for leaving his GF when she's pregnant. I see Tommy as a young man with a lot of girls throwing himself at him and the last thing he wants to do right now is settle down, which he is completely in his own right to do but he should at least have the balls to be honest with Molly and Molly herself should walk in the light of the truth and read the writing on the wall. I don't think either of them really wants to be together; they aren't in a mutually beneficial relationship, it must be very draining to deal with. Yet, as I said before, I lack sympathy for either of them because they are both two grown adults who can easily leave one another with little hassle, much less than a regular couple would. I see the relationship fizzing out completely when the baby hits around the 6 month mark.

OmG is it called XYZ? xx
