Could necessary truths like "red is a color" turn out to be wrong?

I am seeing a married man that had already started his divorce proceedings before we had our affair. His wife is a friend of mine and approves of our relationship because she still wants her husband around for advice and help but she is seeing other men and in fact has a stable relationship with one. I care for this man deeply and he has said he "loves me". From the beginning my guilt about being with a "married man" has haunted me from a religious point of view. I can't get around it. Now we are both in stressful situations where he is going to court (more than once because we are in Mexico and it takes a long time) and I am selling my house with a major issue with the closing. Since we have started to argue, I just want to break it up until his divorce goes through and my closing to get some breathing room. At this point, I don't even want to be with him.

In what extent through the philosophy of time, can it be said that there is no 'past' or 'future.' But that there is a only a eternal 'Now' and if that's the case, how should a philosopher or someone like me be able to explain this idea? Also if there is a eternal 'Now,' then could it be said that the Universe is only, and always present with no future or past.

Can philosophy make you go crazy? If you think too much about philosophy, will you end up not being able to think properly?

Is philosophy something that everyone uses? Should people use philosophy more, than they already do?

Are all philosophical questions unsolvable?

how would i use natural deduction to prove this argument to be correct? Its always either night or day.There'd only be a full moon if it were night-time. So,since it's daytime,there's no full moon right now. i have also formalized the argument using truth functional logic i'm not sure if it is completely correct though and would much appreciate the help. symbolization key: N: night D: day Fm: full moon Nt: night time Dt: day time ((N V D) , (Fm → Nt) , (Dt → ¬Fm))

A yellow chair isn't in the set of chairs because it's yellow. Similarly, a beautiful painting isn't in the set of good paintings because it's beautiful. Is my analogy sound?

I'm leaning toward the position that there is little or no difference between advocacy and lying. Has any other philosopher discussed this in detail?
