Shanethea,
I’ll have to agree with Anita on this, it seems like you may be distracting yourself with Mr Z. If you feel this is a time where you need to focus on yourself, then do it. Especially if this is a pattern which has occurred after previous break-ups.
Mr Z reminds me of someone my friend dated, they planned a European trip after an intense month or two together, only to be incredibly let down soon after by him. His unreliability/aloofness earlier in the relationship, proved to be the undoing of the budding relationship. Just because someone “is very mature and knew what he wanted and how to get it” – doesn’t always equate to the required level of emotional maturity for a long term relationship.
Keep your mind clear from distractions. Keep it all about you at least for a few more months. Walk your whippet up the hills of montpellier if it you have to (its a silly saying – but i like it).
