If my partner is out of the closet and I'm not out yet, will this cause a lot of issues in our relationship?

It may, depending on how important it is to them to be out and how connected they are to your relatives and friends. Even if they agree to pretend around your family, if you all aren't extra careful with social media settings they may find out just by seeing other people's comments on your posts. Besides, if they see you two together they'll probably suspect--at least one or two of them will. Basically if you want to stay closeted in this case you'll need to keep your partner and your family completely separate--preferably don't even mention their existence to your family.

It might, depending on how open your partner is to having a relationship that no one really knows about. It all depends on how you choose to go about this, but by no means should you feel forced to come out by anyone.

If your partner is out of the closest and you aren't yet, this may cause potential issues in your relationship if you two decide to make big relationships commitments to one another. To solve such an issue, you and your partner should together analyze what is keeping you from coming out and take it one step at a time to come out to those around you.

Make sure your partner understands that you are still in the closet, and that they need to respect that, if they can't, that may not be the best relationship for you

Not necessarily! For some people it's a bit hard to have to hide their relationship due to the other not being out yet, but many couples can find a balance fit for the situation, something that works for both. It's important to talk about this, to keep each other updated about your feelings, and to respect each other's needs. Surely your partner can understand why you're not out, if you talk about it. Discussing your feelings and a lifestyle that can meet the needs of both is the key to a successful relationship.

It can be tricky yes, as youve not come out yet they'll be things you won't be comfortable doing yet due to this, but if your partners aware and is supportive and is willing to help you through coming out then things should be fine and they'll be there for you and once your out you can both enjoy the things you should do :)

It will probably cause some issues between the two of you, but it's extremely important to talk to your partner about this. Communication is key. If your partner pressures you to come out when you're not ready, that's a bad thing and you should rethink your relationship, since you want your partner to be a compassionate and empathetic person.

It depends on your partner. In my experience we looked at it as ours and only ours for and 3 months until she felt comfortable with telling her family.

Talk to your partner and come to terms in your relationship that you're both comfortable with. It doesn't have to cause issues if you can find that middle ground.

It really depends on your partner. Sometimes it does not bother them that would be fine. But others can be bothered by this. So talk to your partner to find out whether it is okay if you are not out yet.
