What do I do when my husband ignores me?

Talk to him. Always, always, always talk to him. Communication is the key of everything. If he deny it, take professional help.

You stay calm and relaxed maybe he has just had a rough day today and doesn't really want to talk about it

Just walk away give him some time he will come around its best to give personal space it helps give you and him both time to think and cool off

Just give some time since there might be somethings which might be affecting him. When he is stable talk to him about your feelings.

Try to approach him different way you did and communicate about your issue. Try to listen to him then talk to him later

When he ignores you make sure to understand why he is ignoring you. If it was something that you did be sure to apologize and let him know how your feeling. Marriage isn't easy and we usually need time to calm down others do it differently so don't harass him, even if you tell him and he doesn't respond know that he heard you. Just give him some time.

Communicate - definitely the key to any relationship. Tell him how you feel and perhaps a conversation will open up more insights into why you feel like you're being ignored.

Approach him and ask him why he is ignoring you or if he has recently experienced any problems. Alternatively if things aren't working like that seek a marriage counsellor to help you find out what the problem is and guide you towards a solution.

go talk to my friends and keep myself busy with other things than my husband so that he does not feel I pressure him

Open communication is the best thing in a marriage so you could try telling your husband that you wish he spent more quality time with you and was more invested in listening to your stories about the challenges and concerns you have. If he does not agree with you that he does that infrequently, try to discuss with him why you two have a different understanding regarding the amount of attention each of you need to pay to each other. Hope this is helpful at all:)
