He tried to tell me that it had been sprung on him out of the blue by his mother. After a bit more talking he admitted he had discussed with his mother having her to stay and helping her to get sorted in the UK.
Elizabeth, I would feel very uncomfortable with this situation. Your Partner approached you re this woman’s presence with dishonesty and lack of transparency, and it sounds like you are still being marginalized and your boundaries disrespected.
This has been planned for a good while, yet you were not informed. It feels like they may have previously messaged/video called to get to know one another. He certainly should have already introduced you as his Partner, regardless of the language difference. Instead he is creating distance with his gushing mentionitis and by sidelining you, while they bond over cozy dinners, shopping adventures, and shared culture/language/connections, etc. It sounds coupley, and you are nowhere in sight. In my view, her ‘forgetting’ to bring a towel to the shower and summoning him to supply one smacks of tantalization.
Elizabeth, he knows you’re unsettled. Has he made any efforts today to reassure you? if you plan on staying, there needs to be a serious discussion regarding your valid feelings, as well as the importance of honesty and keeping strong boundaries in the face of flattery, ego validation, and temptation. Furthermore, P needs to be forthcoming about this woman’s plans.
Has he made definite plans to introduce you and to spend quality time with you?
Personally, I would move on because lying and deception in a relationship is a dealbreaker for me.
