(19F) I love my boyfriend (29M), but his porn addiction and lying are breaking me. I need help deciding what to do. We’ve been together for almost 2 years.

I really need your opinion.
Let me start with a bit of backstory.

I met my boyfriend on the subway, and we instantly had a strong connection.
Within two months, we were already living together.

Everything felt perfect until I started catching him lying and constantly watching porn.
Watching porn in general isn’t the issue, but the amount he watched and the fact that I kept catching him doing it — it didn’t feel normal.

We’ve been together for almost 2 years now.
I want to break up with him, but making that decision is really hard for me.

In many ways, our relationship is great:
– We rarely fight over small things
– Our humor matches perfectly
– We understand each other without speaking
– Sometimes I think something and he says it out loud
– He takes care of me, supports me financially, helps around the house
– I truly feel loved and protected with him

But…
He lies constantly. Even about little things.
He scrolls through social media accounts of other girls.
He buys intimate photos/videos from girls online.
I’ve caught him on dating apps many times.

We’ve had huge fights about it, and I’ve forgiven him over and over again.
I realized he’s addicted to porn — and that’s a real problem.

You might think something is wrong in our sex life, but everything is great.
I’ve asked him many times if he’s missing something or wants to try something new — he always says no, that he’s happy.

But when we fight about this, he cries, begs me to forgive him, and says he’s trying to fight the addiction.
In reality, though, he’s doing nothing to actually fight it.
He promises to change, and then within 2–3 days, he’s back to the same things. Sometimes even worse.

During our worst fights, he leaves, contacts other girls, subscribes to more accounts, and repeats the same patterns.

I love him. And aside from this issue, things are honestly really good.
But the way he treats me — lying, sneaking, watching other women — makes me feel unwanted and not beautiful.

The worst part is that I know I’m attractive.
I’ve never had a problem with attention from guys.
But somehow he makes me feel like I’m not enough.

I’m stuck. I don’t know what to do.
Should I leave? Or keep hoping he’ll change?

TL;DR:
I’m (19F) in a nearly 2-year relationship with a guy (29M) I love deeply. He supports me, we get along great, and the connection is strong — but he constantly lies, is addicted to porn, buys explicit content from other girls, and uses dating apps. I’ve forgiven him many times, but nothing changes. I feel unwanted and unattractive, even though our relationship is otherwise good. I don’t know what to do anymore.
