No, you don't continue the relationship because you have no relationship to continue.

First of all, do not blame yourself for what you said in the airport. You said nothing wrong, nothing that was unreasonable and he is totally gaslighting you on that.

Everything he has said to you has been a lie. Do you actually know, as a proven fact, that his mother died? Are you sure?

Do you know 100% he is who he claims to be and hasn't catfished you?

Either way, it's time to cut your losses. There is nothing wrong with meeting and starting as a LDR but you need to meet. 18 months down the line he has done everything he can to avoid doing that, he has gaslit you, demonstrably lied to you if you ever tried to meet him again, you already know it would be exactly the same.

The fact that he blocked you, his girlfriend, on ANY messaging platform is, IMO, unforgivable and an automatic breakup.

No, you don't show up in Hawaii. He won't be there. Go to Chicago, enjoy your holiday, go home a single woman and move on to dating real people

Look, you know what you need to do and it is going to happen eventually anyway.

Yes, you "love" him. But you aren't going to spend your entire life with him and you know that. Your relationship is already a patchwork of compromises and some of those are compromises neither of you should be having to make for a long term relationship.

You don't know if you are lesbian yet because you have yet to have sex with anyone that you really connect with sexually. It might need a woman, but you might feel that connection with a different man. You wont know until you find out.

The love you have for him is not good enough to put aside a lifetime of sexual connection and satisfaction for yourself, and neither is the love he has for you. You realise that you cannot satisfy him as a sexual partner either? Yes, you can have sex with him and make him orgasm. But he has much better sexual experiences ahead of him with someone else who actually wants to sleep with him.

You can't sustain a relationship where you feel disgusted in any way by your partner. You must know this.

Free both of you rather than delaying the inevitable

I'm sorry, this is one of the harshest things I have ever written on Reddit but this marriage and relationship is a joke.

He has absolutely no interest in leaving home. It is ridiculous that he has gotten married to someone and has made no effort to live with them independently. The way you write comes across strongly that he has no interest in leaving his mother's house. Him saying "his love is almost dead" is a whole field of big red flags waving. I wonder how strong it was in the first place; a long distance relationship via the internet sounds ideal for this guy.

Sorry, the way you write it makes your husband sound absolutely useless. Doesn't work, doesn't want to live independently, doesn't want to support his wife and doesn't see his wife as his family.

You are not incorrectly perceiving things; his family don't like you, they are prejudiced against you as an immigrant to the country. They are really skeptical about this relationship and I really don't blame them; it's not like he has been leaping to your defence or showing them he is your priority.

You don't really show us any indication that this man is especially committed to you beyond going through with the promised marriage. You should be his everything and instead, he remains wedded to his family.

I'm not really sure what you can do. You both need to be out of that house and together, but I would be very sure that he actually loves you first, rather than loving the idea of having a partner. I would worry that long distance suited him more.

He needs to get a job and actually be an adult and a husband.
